This is needed when building HWPM driver locally without
NVIDIA build system.
- driver.c: use kernel version check to select the correct
signature of class:devnode
- mem_mgmt_utils.c:
- use kernel version check to provide correct parameter
of MODULE_IMPORT_NS macro
- use kernel version check to select the correct signature
of get_user_pages function
- mem_mgmt_utils.h: use kernel version check to select
between iosys-map or dma-buf-map

This patch fixes issues found during testing
and guidance provided by devtools. The following
is changed in this patch:
1. mcf_iobhx and mcf_ocu are merged into a single mcf_soc IP.
2a. c2c is changed from 2 instances to 1.
2b. Remove C2CS0/1 which are the broadcast apertures.
Also remove the allowlist offset specific to broadcast
aperture.
3. mss_hub is changed from 1 instance to 8.
4. mss_channel is changed from 1 instance to 32.
5. mc0 perfmux is added to mcf_clink.
6. mcf_core is changed from 1 instance to 8.
7. License headers updated where necessary.
8. c2c allowlist updated to have just the offsets common
to all links.
9. Added a verbose comment explaining the design of
th500_hwpm_force_enable_ips()
10. Added back validate_current_config module parameter
as many systems still don't support fuses.
11. If all F's are read back for a regop in ip_readl(),
return -ENODEV.
There is a corresponding patch to update the python scripts
that generated many of the C and header files.

HWPM code from HWPM repo is not currently used to compile with kernel
5.10. However, CL to compile HWPM repo for kernel 5.10 is required to
validate latest changes on Pre-Si.
Since conftest is only available for kernel version later than 5.10.
Add condition to include conftest only if HWPM is used as OOT module.

In Linux v6.2, the 'struct class.devnode()' function was updated to take
a 'const struct device *' instead of a 'struct device *'. A test has
been added to the conftest script to check for this and so instead of
relying on kernel version, use the definition generated by conftest to
select the appropriate function to use.
This is beneficial for working with 3rd party Linux kernels that may
have back-ported upstream changes into their kernel and so the kernel
version checks do not work.

Upstream Linux kernel commit ff62b8e6588f ("driver core: make struct
class.devnode() take a const *") updated the 'devnode' function pointer
under the class structure to take a const device struct. This breaks
building the Tegra HWPM driver with Linux v6.2. Make the necessary
changes to the HWPM driver to fix the build breakage.

Kernel version beyond 5.10 introduces dma_buf_map structure (called
iosys_map in later versions). Kernel virtual address corresponding to a
dma_buf is stored in the dma_buf_map structure.
- This patch updates memory management function to use correct mem bytes
buffer kernel virtual address stored in the corresponding dma_buf_map
structure.
- Use dma_buf_map structure pointer to unmap kernel virtual address.
- During release, poll mem bytes buffer with finite timeout value.
- Add description for use of dma_set_mask_and_coherent.

Property support-soc-tools was added mainly to provide user's control to
enable/disable HWPM feature. Since, the same functionality can be
achieved using "status" in device node, support-soc-tools property is
redundant. Hence, this property is removed from HWPM device node.
Update HWPM driver probe to not depend on support-soc-tools property.

- Make clock reset functions into HALs. This way we can control
clock-reset logic for any chip. Set clock-reset HAL pointers to
appropriate functions.
- Remove clock-reset function wrappers as these will not be required and
corresponding HAL pointers will be used.
- As clock reset init is defined as a HAL, modify probe logic to
initialize chip info before invoking any HALs.
- Move common/primary HAL validation logic to common code and implement
new HAL to validate chip specific HALs. This way we can ensure that HAL
pointers are set as expected.
- Keep only one definition for t234_hwpm_init_chip_info as t234 should
always be initialized and hence only single definition should be
available.
- Expected return value of 0 indicates success and any other value
(mostly negative in current logic) indicates error, compare function
returns with 0 to print error in tegra_hwpm_release().
- Since a build can support both ACPI and device tree, update
init_chip_info() to retrieve chip information from ACPI and device tree
in case of failure.
