wl18xx: read FW pc on recovery
Define the FW pc in the 18xx register translation table. This specific register is only valid in the boot partition, so change the momentarily change partitions. This doesn't damage 12xx cards, where the FW pc is accessible via boot partition as well. Signed-off-by: Arik Nemtsov <arik@wizery.com> Signed-off-by: Luciano Coelho <coelho@ti.com>
