From: Sean Wang <sean.wang at mediatek.com>
For more readability and maintenance, all the clock related DT
nodes for mt7622 SoC are grouped into a separate DT file. And
currently mt7622-clock.dtsi only includes the fixed clock for
uart0 and the oscillator which would be extended after MT7622
clock driver is introduced.
