crypto: msm: qce50: enable BAM SPS_BAM_CACHED_WP
Enable SPS_BAM_CACHED_WP option. The BAM register access is very slow.
The write descriptor offset information in the BAM_P_EVENT_REG is only
set by the host if BAM is runnig in system mode, such as NDP-BAM of crypto.
On each BAM transfter, driver reads the register to figure if
there is enough space to put in new descriptor. Reading the register can be
from driver cache copy, instead of going out to read the register if
SPS_BAM_CACHED_WP option is enabled.
