From: Arnd Bergmann <arnd@arndb.de>
Outside of the EFI tpm code, the TPM_MEMREMAP()/TPM_MEMUNMAP functions are
defined as trivial macros, leading to the mapping_size variable ending
up unused:

In file included from drivers/char/tpm/tpm.h:28:
include/linux/tpm_eventlog.h:167:6: error: variable 'mapping_size' set but not used [-Werror,-Wunused-but-set-variable]
167 | int mapping_size;
Turn the stubs into inline functions to avoid this warning.
Fixes: c46f3405692d ("tpm: Reserve the TPM final events table")
