[PATCH v2 3/5] scsi: ufs: mediatek: Move MTK_SIP_UFS_CONTROL to mtk_sip_svc.h

SMC commands used by multiple drivers need to live in a shared header
file somewhere to avoid code duplication. In order to rework the MPHY
reset control to be in the phy-mtk-ufs.c driver, both ufs-mediatek and
the phy driver need access to this command.

Move it to mtk_sip_svc.h, where other such command definitions already
live.
