msm: wcnss: Add the support to access IRIS registers using bit-bang 



During cold boot, if firmware watchdog bite happens, WCNSS platform driver
will try to log Pronto registers, but in some cases it cannot access them
since there is no clock on Pronto. Add the support to log IRIS registers
using bit-bang in order to debug this issue.
