tpm: Move tpm_buf code to include/linux/

Browse source 
Move tpm_buf code to common include/linux/tpm.h header so that it can
be reused via other subsystems like trusted keys etc.

Also rename trusted keys and asymmetric keys usage of TPM 1.x buffer
implementation to tpm1_buf to avoid any compilation errors.
