Add basic device-tree for the Genio 1200 EVK board. The
Demo board is made by MediaTek and has a MT8395 SoC (MT8195 family),
associated with the MT6359 and MT6360 PMICs, and
the MT7921 connectivity chip.
The IOs available on that board are:
* 1 USB Type-C connector with DP aux mode support
* 2 USB Type-A connector with a USB hub
* 1 micro-USB port for gadget or OTG support
* 1 full size HDMI RX and 1 full size HDMI TX connector
* 1 micro SD slot
* 40 pins header
* SPI interface header
* 1 M.2 slot
* 1 audio jack
* 1 micro-USB port for serial debug
* 2 connectors for DSI displays, 1 of the DSI panel is installed
* 3 connectors for CSI cameras
* 1 connector for a eDP panel
* 1 MMC storage
* 1 Touch Panel (installed DSI display)
* 1 M.2 slot for 5G dongle
This commit adds basic support in order to be able to boot.

Changes for v2:
- correct SOC binding to "mediatek,mt8395".
- Fix a Linux coding style comments for optee node.
- Fix wifi fixed 3.3v power's node with "wifi-3v3-regulator".
- Fix node name of mt6360 and mt6517 to generic dts name as "pmic".
- Remove unecessary blank line.
- Reording usb node as the order of "phy" then "host".
Changes for v3:
- Add back bindings for "mediatek,mt8195".
- Fix wifi fixed 3.3v power's node with "regulator-2"

Please follow the current naming in dts/mediatek/.
This should be `mt8395-genio-1200-evk.dtb`
Fixed.

`mt8195-genio-1200-evk.dts` please
Is this a typo?
I'll get build error if I've actually rename the file name to
'mt8195-genio-1200-evk.dts' which isn't match mt8395-genio-1200-evk.dtb.
(I've tested it to make sure every thing okay.)

I've reordered these node according to alphabet order as could as
possible. I'll send version v4 for reviewing. Thanks
