firmware: arm_ffa: Move the function ffa_features() earlier

Browse Source 
We need to use ffa_features() in ffa_partition_probe() to detect if
the newer FFA_PARTITION_INFO_GET_REGS API is supported in the platform
or not. To avoid unnecessary forward declaration within the file, let
us just move this ffa_features() earlier.

No funtional change.
