platform/x86: amd-pmc: Shuffle location of amd_pmc_get_smu_version()

When CONFIG_DEBUG_FS is disabled, amd_pmc_get_smu_version() is unused:

  drivers/platform/x86/amd-pmc.c:196:12: warning: unused function 'amd_pmc_get_smu_version' [-Wunused-function]
  static int amd_pmc_get_smu_version(struct amd_pmc_dev *dev)
             ^
  1 warning generated.

Eliminate the warning by moving amd_pmc_get_smu_version() to the
CONFIG_DEBUG_FS block where it is used.
