Having "bool ohci" argument bounded us to two cases only and didn't
allow re-using this code for XHCI.
Having "bool ohci" argument in bcma_hcd_create_pdev function limited it
to support two cases only (OHCI and EHCI) and put too much logic in it.
Lets make caller pass all required data. This adds few extra arguments
to the function call but will allow us to reuse this code and handle
more cases in the future (e.g. add XHCI support).

This will allow adding USB 3.0 (XHCI) support cleanly.
This splits one big probing function into two smaller ones. The main one
is now responsible for the generic stuff: allocating memory & enabling
power using GPIO. The new one contains code that is specific to the USB
2.0 bcma core.
This will allow adding support for the USB 3.0 bcma core (handling XHCI)
in the future.
