scsi: ufs-msm: request UFS register space access after power collapse

Following UFS core power collapse, all the TZ programmed xPU protection
settings would be lost and default protection settings won't allow access
to even UFS host controller register address space from non-secure world.
Hence we have to explicitly call into TZ to open up atleast UFS host
controller & UFS PHY register address space access to non-secure world.
