  firmware: arm_ffa: Correct 32-bit response handling in NOTIFICATION_INFO_GET (2025-12-18 14:22:07 +0000)

----------------------------------------------------------------
Arm FF-A updates for v7.0

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.
