Subject: [PATCH v3 07/10] firmware: arm_ffa: Rename ffa_dev_ops as ffa_ops
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.
