drm/amd/ras: preserve CPU MCE context in the log ring

Browse source

Processor CPER generation needs the APIC ID and machine-check bank
number in addition to the ACA register values. Logging the full internal
ACA bank also exceeds the stable fixed-size log body representation.

Carry the APIC ID and bank number with incoming ACA banks and store CPU
MCE events in a compact 128-byte log context for later CPER encoding.
