Due to some old SoCs with shared t-phy only support force-mode switch, and
can't use compatible to distinguish between shared and non-shared t-phy,
add a property to supported it.
But now prefer to use "mediatek,syscon-type" on new SoC as far as possible.
Two questions:
1. Why is it *not* possible to use the compatible string to distinguish between
shared and non-shared T-PHYs?
2. If we really can't use compatibles, what's the reason why we can't use the
"mediatek,syscon-type" property?
