Subject: [PATCH 0/2] Add mtk-sd support for MT8196

There are some new features for Mediatek SoC MT8196, which include new
command/data transmitting and receiving path (abbreviated as tx/rx), and
a new bus design that prevents the CPU from accessing the IP registers
unless the source clock control gate is enabled. Furthermore, some register
settings are also modified.

The driver code has to be adapted to implement the above changes, and the
compatible 'mediatek,msdc-v2' is added to driver and devicetree bindings,
for MT8196 and future compatible SoCs that support new tx/rx.
