[PATCH 10/10] arm64: dts: apple: Enable DockChannel HID on M2 and M3 laptops

[Michael Reeves via B4 Relay]

From: Michael Reeves <michael.reeves077 at gmail.com>

Enable the MTP mailbox, DART, DockChannel mailbox, and HID transport on
the M2 and M3 laptop device trees using this internal input path.

Add a keyboard alias and keyboard child node for each machine so the
transport can expose the internal keyboard.
