The HWPM driver fails to be with Linux v6.13 because of the following
two issues:
1. In Linux v6.13, commit cdd30ebb1b9f ("module: Convert symbol
namespace to string literal") updated the MODULE_IMPORT_NS macro to
take a string literal as an argument in Linux v6.13. Use conftest to
detect if MODULE_IMPORT_NS takes a string literal as an argument and
update the HWPM driver accordingly.
2. The following build error is observed:
In file included from os/linux/clk_rst_utils.c:17:
include/linux/reset.h:30:49:
error: implicit declaration of function ‘BIT’
[-Werror=implicit-function-declaration]
30 | #define RESET_CONTROL_FLAGS_BIT_ACQUIRED BIT(2)
| ^~~
Fix the above by including the 'bits.h' header file.

- 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.
