[PATCH v4 15/25] scsi: ufs: mediatek: Remove mediatek,ufs-broken-rtc property

This flag property was never described in the binding, and its
capability wrapper seems pointless.

If one of the MediaTek SoCs needs the ufshcd quirk applied, then this
can be done per-compatible, without needing to give the device tree
author the option to forget to set it.

Remove it and the associated capability flag wrapping code.
