Abhi.Singh 36e3d877cd feat(tpm): add tpm drivers and framework
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.
