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:
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
