Subject: [RFC PATCH v2 3/3] arm64: dts: mt8195: add USB related nodes
Add USB nodes, PHY nodes and some fixed regulator nodes.
We prefer to use mt8192's compatible for the first USB controller
(port0), there is no wrong with the SOF/ITP interval; but for other
controllers (port1~port3) should use mt8195's one due to the wrong
default setting of SOF/ITP interval which should be calculated from
48M, but not 24M by default.
