Remove dependencies on the following deprecated
nvhost API functions by implementing their functionality
directly in the NVDLA driver:
1. nvhost_module_init:
Replaced with direct implementation in nvdla_module_init:
- Get clock resources and set clock rates
- Initialize reset control
- Set up power management runtime
- Create debugfs entries
2. nvhost_module_deinit:
Replaced with direct implementation in nvdla_module_deinit:
- Disable power management runtime
- Free falcon firmware if present
- Clean up debugfs entries
3. nvhost_module_reset:
Replaced with direct implementation in nvdla_module_reset:
- Handle prepare_poweroff callback
- Acquire and release reset control
- Load clock gating registers
- Handle finalize_poweron callback
4. nvhost_module_busy:
Replaced with direct implementation in nvdla_module_busy:
- Get PM runtime sync
- Handle PM runtime errors
5. nvhost_module_idle and nvhost_module_idle_mult:
Replaced with direct implementations:
- Mark last busy for PM runtime
- Handle autosuspend or regular PM runtime put
6. nvhost_module_pm_ops:
Replaced with custom nvdla_pm_ops structure:
- Implement nvdla_runtime_suspend and nvdla_runtime_resume
- Implement nvdla_suspend and nvdla_resume
- Configure SET_RUNTIME_PM_OPS and SET_SYSTEM_SLEEP_PM_OPS
7. nvhost_module_load_regs:
Replaced with nvdla_module_load_regs:
- Implement register manipulation with direct memory mapped I/O
- Use writel instead of host1x_writel

Replace deprecated nvhost client device functions with
their direct implementations to maintain compatibility
with newer host1x drivers:
1. Replace nvhost_client_device_get_resources with
direct implementation:
- Get host1x data from parent device
- Map device resources directly
2. Replace nvhost_client_device_init with
nvdla_client_device_init:
- Allocate character device region
- Create device node using nvdla_client_device_create
3. Replace nvhost_client_device_release with
nvdla_client_device_release:
- Clean up device node
- Unregister character device region
This change ensures the NVDLA driver continues to work
correctly with the host1x driver while removing
dependencies on deprecated functions.The device node
"nvhost-ctrl-dla" is still created with the same
functionality as before.

Replace the deprecated nvhost_syncpt_unit_interface_init()
function with host1x_syncpt_get_shim_info() in
the NVDLA driver. This change:
1. Adds a local def of struct nvhost_syncpt_interface
2. Implements the functionality in nvdla_sync_syncpt.c
3. Adds necessary include files for IOMMU and DMA mapping
This change ensures the NVDLA driver continues to work

This change adds SC7 wake support to cec driver.
CEC engine can detect TV packets in SC7 state and
can wake up when particular pattern detected.
In resume functionality, the total arrived packets on FIFO
needs to read and reported back to user-space.
This change adds -
1. Program CEC engine to activate for SC7 wake.
2. Program required opcode and physical address.
3. Register for wake and read packets in resume path.
4. Provide sysfs control to program physical address.
Verification of SC7 wake is done for below cases -
1. TV turn on and off is tested.
2. TV source input change is tested.
3. CEC Analyzer set-stream is tested.

Calling tegra_camrtc_reboot() can cause a memory fabric timeout error by
asserting reset when the RTCPU is in the middle of a memory transaction.
As a solution (similar to tegra_camrtc_halt), before asserting the
hardware reset, signaling the RTCPU to suspend its operations using
CAMRTC_HSP_BYE and waiting for RTCPU to enter WFI.

Previous implementation lacks of documentation and it's hard to
understand the effect of changing specific tunable parameter.
Revise the implementation so that the scaling behavior is somehow
aligned with the tegra_wmark governor supported by the actmon. The
only different is that nvhost_podgov governor is polling-based DFS
algorithm and it maintaines the moving average load in the governor
instead of hardware itself.

The Tegra264 PCIe drivers don't build for kernels that don't have:
1. The structure mrq_pcie_request_req defined
2. The function pci_epc_deinit_notify() present
This is currently being handling by building a dummy driver for kernels
that don't have these. To simplify this, use conftest to detect if the
above are present and modify the Tegra264 PCIe driver accordingly if
they are not present. By using conftest we can remove the Makefile
variable 'NV_OOT_PCIE_T264_SOC_SKIP_BUILD' and ccflag
'DNV_CONFIG_PCIE_TEGRA_DMA_DISABLE'.
Finally, the PCIe drivers are always built as modules so simplify the
Makefile and remove the usage of 'CONFIG_TEGRA_OOT_MODULE'.

NvRmMemRead/NvRmMemWrite APIs don't have corresponding requirements in
DriveOS 7.0 Linux NSR. We have taken sign-off from the stakeholders to
confirm that they are not using these APIs in T264 Linux Prod NSR
variant. But some of them are using these APIs in dev_nsr and did not
agree to remove it from dev-nsr, L4T, HOS etc. Hence we need to
make sure that they do not accidentally start using these APIs. Add
bug_on when the corresponding ioctl is called in prod_nsr.
