Add tpm2 drivers to tf-a with adequate framework -implement a fifo spi interface that works with discrete tpm chip. -implement tpm command layer interfaces that are used to initialize, start and make measurements and close the interface. -tpm drivers are built using their own make file to allow for ease in porting across platforms, and across different interfaces.
