security/tpm: Add vendor-specific tis functions to read/write TPM regs
In order to abstract bus-specific logic from TPM logic, the prototype
for two vendor-specific tis functions are added in this
patch. tis_vendor_read() can be used to read directly from TPM
registers, and tis_vendor_write() can be used to write directly to TPM
registers.
