iwlwifi: move prph handling into the transport

Browse Source 
New transports may handle it internally for better performance.
Also move the tracing inside PRPH access which will make the
output more readable:

iwlwifi_dev_ioread_prph32: Read 0x0 from SCD_AGGR_SEL (32-bit)

instead of the corresponding accesses to HBUS_TARG_PRPH_*.
