msm: camera: icp: Support multiple HFIs

Browse Source

During probe, each hw mgr register as a client to HFI layer and share
the handle to icp core layer to book keep. HFI register routine searches
for a free hfi slot to dynamically allocated hfi info struct and returns
a client handle to the caller. During open sequence, HW mgr is required to
initialize the hfi using the handle obtained from the registering in boot
up. Upon unregistering, the hfi slot and the hfi info memory is freed.
Hw mgr layer can invoke the existing hfi interfaces by passing hfi handle
to fetch the right hfi info. With this change, each hw mgr can
independently run on one HFI to interact with FW.

Add support in enabling OFE PC and config OFE UBWC in hfi layer, and parse
OFE UBWC config values from DT.
