usb: fotg210: Acquire memory resource in core
The subdrivers are obtaining and mapping the memory resource
separately. Create a common state container for the shared
resources and start populating this by acquiring the IO
memory resource and remap it and pass this to the subdrivers
for host and peripheral.
