scsi: ufs-msm: disable the sigdet before power collapsing PHY
If UFS PHY power down is deasserted and power is restored to analog
circuits, the rx_sigdet can glitch. If the glitch is wide enough,
it can trigger the PHY digital logic to think it saw a DIF-N and
cause it to exit Hibern8. Disabling the rx_sigdet during power-up
will mask the glitch.
