[RFC v1 2/5] drm/xe/fwctl: Add uAPI definitions for Xe FWCTL support

["Anoop, Vijay" <anoop.c.vijay@intel.com>]

From: Anoop Vijay <anoop.c.vijay@intel.com>

Add Xe-specific uAPI definitions for FWCTL support. Introduce
include/uapi/fwctl/xe.h to describe userspace ABI for Xe firmware
control operations, and extend core FWCTL uAPI to recognize
Xe device type.

This patch adds uAPI definitions only. No functional kernel code
is introduced.
