x86/platform/pmc_atom: Fix warning when CONFIG_DEBUG_FS=n

When compiling with CONFIG_DEBUG_FS=n, GCC emits an unused
variable warning for pmc_atom.c because "ret" is used only
within the CONFIG_DEBUG_FS block.

This patch adds a dummy #ifdef for pmc_dbgfs_register() when
CONFIG_DEBUG_FS=n to simplify the code and remove the warning.
