regulator: qpnp-labibb: modify IBB_SPARE_CTL setting during TTW mode exit 



Currently for PMI8996, IBB_SPARE_CTL is configured to slower PFET turn off
while exiting out of TTW mode. As per the hardware documentation, this
setting needs to be modified to faster PFET turn off for both PMI8996,
PMI8994 and PMI8950. Modify it to improve IBB efficiency.
