FROMGIT: ufs: add a quirk not to use default unipro timeout values

Browse Source 
Unipro specification says attribute IDs of the following
thing are vendor-specific values, so some SoCs could have
no regions at the defined addresses
- DME_LocalFC0ProtectionTimeOutVal
- DME_LocalTC0ReplayTimeOutVal
- DME_LocalAFC0ReqTimeOutVal

The following things should be set considering the compatibility
between host and device, so those values must not be fixed and
you could use reset values or vendor specific values
- PA_PWRMODEUSERDATA0
- PA_PWRMODEUSERDATA1
- PA_PWRMODEUSERDATA2
- PA_PWRMODEUSERDATA3
- PA_PWRMODEUSERDATA4
- PA_PWRMODEUSERDATA5
