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
