nfit: Mark some functions as __maybe_unused 



On arm64 little endian allyesconfig:

drivers/acpi/nfit/intel.c:149:12: warning: unused function 'intel_security_unlock' [-Wunused-function]
static int intel_security_unlock(struct nvdimm *nvdimm,
           ^
drivers/acpi/nfit/intel.c:230:12: warning: unused function 'intel_security_erase' [-Wunused-function]

4 warnings generated.

Mark these functions as __maybe_unused because they are only used when
CONFIG_X86 is set.
