brcmfmac: allow GCI core enumuration
GCI core is needed for ULP operation. Allow GCI core enumuration with
below changes:
- Allow GCI to be added to core list even when it doesn't have a wrapper.
- Allow 8K address space size.
- Don't overwrite the address value when an additional size descriptor
is in place.
