tegra: hwpm: Fix build for Linux v6.13

Browse Source 
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.
