iwlwifi: move prph handling into the transport
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_*.
