add the Infineon Optiga SLB9670 TPM2.0 GPIO SPI
configuration data, as well as chip reset and the
GPIO SPI bitbang driver initialization. This code
supports use with the rpi3 platform, with availibility
to add configuration parameters for other platforms

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.
