Arm FF-A updates for v7.0

Browse source 
A small set of updates to the Arm FF-A driver:
 
 1. Fix a correctness issue in NOTIFICATION_INFO_GET handling of 32-bit
    firmware responses, avoiding reads from undefined register bits.
 
 2. Improve clarity and robustness of FF-A feature checks by tying them
    to explicit version requirements.
 
 3. Ensure Rx/Tx buffers are unmapped on FF-A initialization failure to
    prevent resource leaks.
