scsi: smartpqi: Fix byte aligned writew for ARM servers
Correct OOPs on ARM servers during driver init.
The driver attempts to update FW with max_feature_supported value using a
writew() kernel call using a byte aligned address. This fails on some ARM
systems.
Change the writew() to two writeb() calls to update this value.
