drm/xe/xe_late_bind_fw: Initialize late binding firmware

Browse source

Search for late binding firmware binaries and populate the meta data of
firmware structures.

v2 (Daniele):
 - drm_err if firmware size is more than max pay load size
 - s/request_firmware/firmware_request_nowarn/ as firmware will
   not be available for all possible cards
v3 (Daniele):
 - init firmware from within xe_late_bind_init, propagate error
 - switch late_bind_fw to array to handle multiple firmware types
v4 (Daniele):
 - Alloc payload dynamically, fix nits
v6 (Daniele)
 - %s/MAX_PAYLOAD_SIZE/XE_LB_MAX_PAYLOAD_SIZE/
