scsi: ufs: pltfrm: Disable runtime PM during removal of glue drivers
When the UFSHCD platform glue drivers are removed, runtime PM should be
disabled using pm_runtime_disable() to balance the enablement done in
ufshcd_pltfrm_init(). This is also reported by PM core when the glue driver
is removed and inserted again:
ufshcd-qcom 1d84000.ufshc: Unbalanced pm_runtime_enable!
So disable runtime PM using a new helper API ufshcd_pltfrm_remove(), that
also takes care of removing ufshcd. This helper should be called during the
remove() stage of glue drivers.
