arm64: allwinner: sun50i: Sync H6 dts(i) files from Linux

Usually the Linux dts changes were synced in specific tags in Allwinner,
to keep track for whats been synced so-far and plan for future syncs.

But this patch sync sun50i-h6* dts(i) files from Linux w/o any specific
tag since these dts(i) changes are required for new H6 boards support.

Linux commit details about the sun50i-h6* sync:
"arm64: dts: allwinner: h6: move MMC pinctrl to dtsi"
(sha1: 6ba2e45d57afdfd982d12f168edd6a79a65075d8)

Linux commit details about the sun8i-tcon-top.h sync:
"dt-bindings: display: sunxi-drm: Add TCON TOP description"
