scsi: ufs: Add a quirk to permit overriding UniPro defaults
[ Upstream commit b1d0d2eb89d4e3a25b212a9d836587503537067e ]
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.
