This patch introduces System Controller (sysctrl) component for Intel Xe3p dGPU platforms.

This component provides the foundational infrastructure for communication
with the System Controller firmware using MKHI protocol over a mailbox interface.

Key features introduced:
- Detection and initialization of System Controller interface on Xe3p dGPU platforms
- Mailbox communication with System Controller firmware
- Fragmented message transfer for large command payloads

This implementation establishes the base for future System Controller feature
enablement and firmware command handling.
