Add functional test cases for the FF-A support
These tests rely on the FF-A sandbox emulator and FF-A sandbox driver which help in inspecting the FF-A communication.

Changelog: ===============
v12:
* remove use of dscvry_info * drop use of calloc when querying SPs * address nits
v11:
* drop unmapping test (taken care of by the DM when removing the device) * address nits
v10:
* use the FF-A driver Uclass operations * use uclass_first_device() * replace CONFIG_SANDBOX_FFA with CONFIG_ARM_FFA_TRANSPORT * address nits
v9: align FF-A sandbox tests with FF-A discovery through DM
v8:
* update partition_info_get() second argument to be an SP count * pass NULL device pointer to the FF-A bus discovery and operations
v7: set the tests to use 64-bit direct messaging
v4: align sandbox tests with the new FF-A driver interfaces and new way of error handling
v1: introduce sandbox tests
