[PATCH] [V2] Add MagicBox M16S support

[Zhang Ning]

changelog and notes:
in V1 emails, I digged some info from vendor OS:

gpio key is added in this version.

gpio i2c is ignored, due to device under this bus is gpio-edid, mainline
kernel can get edid correctly, thus ignored.

GPIODV_2 is sdio_pwrseq reset pin, and it is active low. I tried active
high firstly, and no wifi. This also fixes wifi lost after reboot.

btrfkill gpio: GPIO_17, is not add in this version, marvell,sd8897-bt
don't have this rfkill property. leave it in my todo list. bt works
well.

GPIOX_7 is used as wifi interrupt in vendor OS, but meson gpio can't be configured as
interrupt, dtb compile warning. thus ignored. wifi works well.

other pins are already correctly handled.

and waiting for GPIO_TEST_N ready for gpio-leds. (should I add it now?)

ir decoder and keymap are still unknown, I can't get info from
vendor OS. leave it in my todo list.
