[PATCH v3 1/2] scsi: ufs: pass device information to apply_dev_quirks

[Stanley Chu]

Pass UFS device information to vendor-specific variant callback
"apply_dev_quirks" because some platform vendors need to know such
information to apply special handlings or quirks in specific devices.

In the same time, modify existed vendor implementations according to
the new interface for those vendor drivers which will be built-in
or built as a module alone with UFS core driver.
