[PATCH v7 0/9] Introducing firmware late binding

[Badal Nilawar]

Introducing firmware late binding feature to enable firmware loading
for the devices, such as the fan controller and voltage regulator,
during the driver probe.
Typically, firmware for these devices are part of IFWI flash image but
can be replaced at probe after OEM tuning.

v2:
 - Dropped voltage regulator specific code as binaries for it will not
   be available for upstreaming as of now.
 - Address review comments
v3:
 - Dropped fwctl patch for now
 - Added new patch to extract binary version
 - Address v2 review comments
v4:
 - Address v3 review comments
v5:
 xe_kmd:
 - Dropped mutex is worker flush in unbind blocking component
   removal while fw download is in progress
 - Handled the fw load in all 3 scenarios (probe, system resume, rpm resume)
   by holding rpm wake ref in outer bounds of worker.
 mei:
 - Most of the review comments
v6:
 - rebased
 - Disabled fw load upon error
v7:
 xe_kmd:
 - resolved kernel doc warnings
 mei:
 - Address v6 review comments (greg kh)

 - Dropped patch 10
