963287e483 MIPS: ingenic: DTS: Add memory info of GCW Zero 
Add memory info of the GCW Zero in its devicetree. The bootloader
generally provides this information, but since it is fixed to 512 MiB,
it doesn't hurt to have it in devicetree. It allows the kernel to boot
without any parameter passed as argument.

b1bfdb6605 MIPS: ingenic: DTS: Update GCW0 support 
Add support for the face buttons, the ACT8600 PMUC, the LCD panel
with backlight, the rumble, internal/external SD readers, and other
things.

Note that the otg-phy node was dropped in the process as it was neither
useful nor used, and was inside a non-compliant board "bus".
