[PATCH] tpm_bios: needs more securityfs_ functions

tpm_bios.c needs securityfs_xyz() functions.

Does include/linux/security.h need stubs for these, or should
char/tpm/Makefile just be modified to say:

ifdef CONFIG_ACPI
ifdef CONFIG_SECURITY
	obj-$(CONFIG_TCG_TPM) += tpm_bios.o
endif
endif

There are also some gcc and sparse warnings that could be fixed.
