Introduce quirks for Samsung UFS devices to modify the PA TX HSG1 sync

For what purpose, these quirks are required ? Is there any problem statement which you can mention first ?

Additionally, Samsung UFS devices require extra time in hibern8 mode
before exiting, beyond the standard handshaking phase between the host
and device. Introduce a quirk to increase the PA_HIBERN8TIME parameter
by 100 µs to ensure a proper hibernation process.
