wlcore/wl12xx: add prepare_read hw op for Rx data

The only difference in the read_data operations is that some chips
need to prepare the data to be read before reading.  So instead of
having a mandatory read_data operation, we now have an option
prepare_data operation that only needs to be implemented for chips
that require it.

In the wl12xx lower driver, we only set the prepare_data operation for
wl127x chips.
