🐛 Bug Fixes

[Rebase \& FF] Fix MP management tests @kuqin12 (#748)

Change Details

Description

The old implementation worked with 2405 release branches, but failed to pass certain cases with 2502.

This change also fixes a few issues with the MP management module:

1. Removes the original code path that will directly invoke the MP service protocol from AP routines. This is specifically not allowed according to the specification. 2. Fixes an issue if HCR enables the exception trapping, while the VBAR is left empty, which will cause the system to fault into EL3.
