firmware: arm_ffa: Split up ffa_ops into info, message and memory operations
In preparation to make memory operations accessible for a non
ffa_driver/device, it is better to split the ffa_ops into different
categories of operations: info, message and memory. The info and memory
are ffa_device independent and can be used without any associated
ffa_device from a non ffa_driver.
However, we don't export these info and memory APIs yet without the user.
The first users of these APIs can export them.
