scsi: ufs: Add a quirk to permit overriding UniPro defaults

The UniPro specification states that attribute IDs of the following
parameters are vendor-specific so some SoCs could have no regions at the
defined addresses:

 - DME_LocalFC0ProtectionTimeOutVal
 - DME_LocalTC0ReplayTimeOutVal
 - DME_LocalAFC0ReqTimeOutVal

In addition, the following parameters should be set considering the
compatibility between host and device.

 - PA_PWRMODEUSERDATA0
 - PA_PWRMODEUSERDATA1
 - PA_PWRMODEUSERDATA2
 - PA_PWRMODEUSERDATA3
 - PA_PWRMODEUSERDATA4
 - PA_PWRMODEUSERDATA5

Introduce a quirk to allow vendor drivers to override the UniPro defaults.
