tpm: Merge the tpm-bios module with tpm.o
Now that we can have multiple .c files in the tpm module there is no reason for tpm-bios. tpm-bios exported several functions: tpm_bios_log_setup, tpm_bios_log_teardown, tpm_add_ppi, and tpm_remove_ppi. They are only used by tpm, and if tpm-bios is built then tpm will unconditionally require them. Further, tpm-bios does nothing on its own, it has no module_init function. Thus we remove the exports and merge the modules to simplify things. The Makefile conditions are changed slightly to match the code, tpm_ppi is always required if CONFIG_ACPI is set.
