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.
