Manish Pandey 7aea1517fb scsi: ufs: Introduce quirk to extend PA_HIBERN8TIME for UFS devices 
[ Upstream commit 569330a34a ]

Samsung UFS devices require additional time in hibern8 mode before
exiting, beyond the negotiated handshaking phase between the host and
device.  Introduce a quirk to increase the PA_HIBERN8TIME parameter by
100 µs, a value derived from experiments, to ensure a proper hibernation
process.
