scsi: ufs: core: Add support for reinitializing the UFS device

Browse source

Some platforms like Qcom, requires the UFS device to be reinitialized after
switching to maximum gear speed. So add support for that in UFS core by
introducing a new quirk (UFSHCD_CAP_REINIT_AFTER_MAX_GEAR_SWITCH) and doing
the reinitialization, if the quirk is enabled by the controller driver.
