[PATCH 1/2] platform/x86/intel/pmc: Mark arl_d3_fixup() and arl_resume() as static

[Nathan Chancellor <nathan@kernel.org>]

With -Wmissing-prototypes, there are two instances flagged with no
prototypes:

  drivers/platform/x86/intel/pmc/arl.c:680:6: error: no previous prototype for 'arl_d3_fixup' [-Werror=missing-prototypes]
    680 | void arl_d3_fixup(void)
        |      ^~~~~~~~~~~~
  drivers/platform/x86/intel/pmc/arl.c:685:5: error: no previous prototype for 'arl_resume' [-Werror=missing-prototypes]
    685 | int arl_resume(struct pmc_dev *pmcdev)
        |     ^~~~~~~~~~
  cc1: all warnings being treated as errors

These functions are not used outside of this translation unit, so mark
them as static to fix the warning.
