platform/x86/amd/pmf: Update PMF Driver for Compatibility with new PMF-TA

[ Upstream commit 376a8c2a ]

The PMF driver allocates a shared memory buffer using
tee_shm_alloc_kernel_buf() for communication with the PMF-TA.

The latest PMF-TA version introduces new structures with OEM debug
information and additional policy input conditions for evaluating the
policy binary. Consequently, the shared memory size must be increased to
ensure compatibility between the PMF driver and the updated PMF-TA.

To do so, introduce the new PMF-TA UUID and update the PMF shared memory
configuration to ensure compatibility with the latest PMF-TA version.
Additionally, export the TA UUID.

These updates will result in modifications to the prototypes of
amd_pmf_tee_init() and amd_pmf_ta_open_session().
