The PMF driver will allocate shared buffer memory using the
tee_shm_alloc_kernel_buf(). This allocated memory is located in the
secure world and is used 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.
