[PATCH 1/2] dt-bindings: remoteproc: mediatek: Fix optional reg-names for mtk, scp

The SCP has three memory regions: sram, l1tcm and cfg. Only sram is
required, the other two are optional. Fix the dt-binding so that the
optional regions can be omitted and passed in any order.

Also add the missing minItems to the reg property and update the
description.
