arm64: dts: meson-s4-s905y4-khadas-vim1s: add initial device tree

Browse Source 
The Khadas VIM1S uses the Amlogic S905Y4 SoC, based on the
Amlogic S4 SoC family, on a board with the same form factor as the
VIM/VIM2/VIM3/VIM4 models. Serial debug console, ethernet, SD card
work with this initial device tree.

It features:
 - 2GB LPDDR4 RAM
 - 16GB eMMC 5.1 storage
 - 32MB SPI flash
 - 100M Ethernet
 - AP6256 Wireless (802.11 a/b/g/n/ac, BT5.0)
 - HDMI 2.1 video
 - 2x USB 2.0 ports
 - 1x USB-C (power) with USB 2.0 OTG
 - 2x LED's (1x red, 1x white)
 - 3x buttons (power, function, reset)
 - IR receiver
 - 40pin GPIO Header
 - 1x micro SD card slot
