The reset described is the phy reset so it should be named ufsphy, so
update it and add the UFS card reset

Earlier reset description was incorrect as phy reset was pointed to
'rst' as well as 'ufsphy' so both phy and core attempted to reset this
causing UFS to not come up. This was discovered with 870b1279c7a0
("scsi: ufs-qcom: Add reset control support for host controller")
