Subject: [PATCH v4 17/25] scsi: ufs: mediatek: Add vendor prefix to
 clk-scale-up-vcore-min

Device Tree properties other than the standard properties must be
prefixed with the vendor's name. The "clk-scale-up-vcore-min" property,
which this driver uses, and the binding did not previously document,
lacked a vendor prefix.

Add the missing "mediatek," vendor prefix and clean up the error print.
No judgements are made regarding the use the property itself, it may
turn out to be implementing something that it should do through a
different way (e.g. OPPs).
