p1022ds: fix switching of DIU/LBC signals
On the P1022, the pins which drive the video display (DIU) are muxed with the local bus controller (LBC), so if the DIU is active, the pins need to be temporarily muxed to LBC whenever accessing NOR flash. The code which handled this transition is checking and changing the wrong bits in PMUXCR. Also add a follow-up read after a write to NOR flash if we're going to mux back to DIU after the write, as described in the P1022 RM.
