Subject: [PATCH net-next v2 1/3] net: phy: mediatek: Add 2.5Gphy firmware dt-bindings and dts node

From: Sky Huang <skylake.huang@...iatek.com>

Add 2.5Gphy firmware dt-bindings and dts node since mtk-2p5ge
driver requires firmware to run. Also, update MAINTAINERS for
MediaTek's built-in 2.5Gphy dt-bindings and change MAINTAINER's name.
