firmware: arm_ffa: Rename ffa_dev_ops as ffa_ops

Browse Source 
Except the message APIs, all other APIs are ffa_device independent and can
be used without any associated ffa_device from a non ffa_driver.

In order to reflect the same, just rename ffa_dev_ops as ffa_ops to
avoid any confusion or to keep it simple.
