[PATCH 3/5] ARM: dts: mediatek: Add basic support for Amazon ford board

[Zakariya Hadrami via B4 Relay]

From: Zakariya Hadrami <zkh1@proton.me>

This tablet uses a MediaTek MT8127 system-on-chip with 1GB of RAM.
It can currently boot into initramfs with a working UART and
Simple Framebuffer using already initialized panel by the bootloader.

Please organize the patch documenting the compatible (DT bindings)
before the patch using that compatible.

This is an automated instruction, just in case, because many review
tags are being ignored. If you know the process, just skip it entirely
(please do not feel offended by me posting it here - no bad intentions
intended, no patronizing, I just want to avoid wasted efforts). If you
do not know the process, here is a short explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new
versions of patchset, under or above your Signed-off-by tag, unless
patch changed significantly (e.g. new properties added to the DT
bindings). Tag is "received", when provided in a message replied to you
on the mailing list. Tools like b4 can help here ('b4 trailers -u ...').
However, there's no need to repost patches *only* to add the tags. The
upstream maintainer will do that for tags received on the version they
apply.
