[PATCH v2 1/3] dt-bindings: mailbox: mediatek,gce-mailbox: add mt6572

[Roman Vivchar via B4 Relay <devnull+rva333.protonmail.com@kernel.org>]

From: Roman Vivchar <rva333@protonmail.com>

Add a compatible string and a header for the GCE constants.

Signed-off-by: Roman Vivchar <rva333@protonmail.com>

There's also 'other' subsystem which covers 0x16XXXXXX range, however
mt6572 doesn't seem to have any MMIO there. It's not included in this
patch.
