  firmware: arm_ffa: Split up ffa_ops into info, message and memory operations (2022-09-08 11:34:04 +0100)

----------------------------------------------------------------
Arm FF-A firmware driver updates for v6.1

Small set of changes in preparation to add support for FF-A v1.1
specification later. It mainly contains:

1. Splitting up ffa_ops into different categories namely information,
   message and memory. It helps to make info and memory operations
   independent from ffa_device so thata generic memory management
   module can use it without specific ffa_dev.
2. Adds support for querying FF-A features and use the same to detect
   the support for 64-bit operations.
3. Adds v1.1 get_partition_info support and use the same to set up
   32-bit execution mode flag automatically.
4. Adds pointer to the ffa_dev_ops in struct ffa_dev and drop
   ffa_dev_ops_get() which enables to drop ffa_ops in optee_ffa
   structure using ffa_dev->ops directly. Additionally ffa_dev_ops is
   renamed as ffa_ops.
