[PATCH -next] platform/x86: intel_pmc_core: fix build error without CONFIG_DEBUG_FS

[Chen Zhou]

If CONFIG_DEBUG_FS is n, build fails:

drivers/platform/x86/intel_pmc_core.c: In function pmc_core_resume:
drivers/platform/x86/intel_pmc_core.c:1327:3: error: implicit declaration of function pmc_core_slps0_display; did you mean pmc_core_is_pc10_failed? [-Werror=implicit-function-declaration]
   pmc_core_slps0_display(pmcdev, dev, NULL);
      ^~~~~~~~~~~~~~~~~~~~~~

Function pmc_core_slps0_display() is responsible for displaying debug
registers, which is under CONFIG_DEBUG_FS.

Providing the static inline stub whenever CONFIG_DEBUG_FS is disabled
to fix this. Function pmc_core_lpm_display() is the same.
