In Linux v6.13, commit 94a20fb9af16 ("sysfs: treewide: constify
attribute callback of bin_attribute::mmap()") changed the type of the
'struct bin_attribute' argument of the bin_attribute:mmap function
pointer to const. Use conftest to detect if this argument is const or
not in the kernel the driver is being compiled against to fix the build.

During SC7 tsec driver is unable to find the desc file for the
tsec fw and thus tsec boot fails. This might result into system
hang. Hence this change adds the tsec fw desc file path as the
module firmware so that the firmware is available to it during
SC7.

This change includes below -
1. For T23x, CEC engine is moved to AON partition. As AON partition
does not powergate, skip all powergate/unpowergate calls for t23x.
2. The clock on which CEC engine operates, 32k/rtc_clk, it is always
running clock in AON partition. So skip clock enable/disable APIs.
3. This change also skips calls to TEGRA DC engine which is not available
from T23x.
4. RX Buffer size is increased to 64 depth from 1 depth. So new register is
provided to program depth so that interrupt gets triggered when certain
depth is filled. By default it is 64 depth so program it to 1 depth
to match old behavior.
5. When tegradc is absent, read physical address from SPARE register which
will be populated by UEFI.
6. This change also adds new register definitions in header file which
needs to program when adding support for CEC SC7 wakeup.
7. Timing registers updated for T23x as per HW guidelines.
8. Some initialization code is changed for T23x.
9. Add devicetree binding documentation.

Add genpd/pm_runtime support to handle power domains
in Tegra Display driver. Also updated CEC and HDA_DC
drivers to add pm_runtime calls.
Added new APIs in CEC and SOR drivers to abstract
calls to pm_runtime and tegra_powergate APIs based
on specific Kernel version. Guarded powergate_id
with CONFIG_TEGRA_POWERGATE since its not needed
when pm_runtime APIs are used, and the powergate IDs
are defined in tegra_powergate.h which is not used
in K5.9.
Removed pm_runtime autosuspend setting since display
driver doesn't assign PM suspend/resume hooks at
present. Suspend/resume calls are linked to platform
device callbacks.
Removed pm_runtime_enable() call in dc_common probe
since there's logically no need of power-domains
in dc_common and also there is no power-domains node
in display_hub node in device-tree. Same with DSI.
All the power-domains handled by each DC are listed
in "power-domains" and "power-domain-names" properties
under respective dc nodes in device tree.

This change fixes below follow-up issues with the earlier fix
to access_ok() API done as part of
https://git-master.nvidia.com/r/c/linux-nvidia/+/2361042:
1. Definition of VERIFY_READ and VERIFY_WRITE have been removed
after K4.14. Hence, used them only for kernel versions < K5.4.
2. Changed access_type parameter of tegra_cec_access_ok() API
to bool. WRITE or READ will be chosen based on the bool value.
3. In the last CL, VERIFY_WRITE was changed to VERIFY_READ in
two access_ok() calls by mistake. Corrected them in this CL.
4. Defined access_type variable with attribute __maybe_unused
since gcc doesn't seem to consider a variable as used if only
passed as function parameter.

There are two type of temp WARs in the nvidia repo:
1) Some functions are defined in driver files that depend on
CONFIG_TEGRA_GRHOST_NVCSI. So these function call should
have dependency protection in the header file.
2) The powergate header file is adding an unnecessary define
check for tegra194-powergate.h and this broke two places
that were referring one of the defines in it.
So this change fix the WARs above by:
a) Removing those temp WARs by adding dummy NOP functions for
those platofrms that don't have CONFIG_TEGRA_GRHOST_NVCSI.
b) Removing the define check in tegra194-powergate.h and the
version check when referring TEGRA194_POWER_DOMAIN_DISP.
