This adds dt-binding documentation for MediaTek MT7622 SoC
which currently only includes basic items such as ARM CPU,
MediaTek SYSIRQ and UART.

Just note that cache geometry detection from architected registers are
removed from v4.12 and hence needs to be specified in DT if you expect
it to show up in sysfs.

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.
