Daniel Golle 7d256aff7b mediatek: update MediaTek PHY patchset 
The previous iteration of MediaTek's PHY patches caused various weird bugs.
Drop culprit patch 733-10-net-phy-mediatek-Extend-1G-TX-RX-link-pulse-time.patch
and use the most recent iteration of the patchset which has been posted to the
netdev mailing list.

Subject: [PATCH 1/9] net: phy: mediatek: Re-organize MediaTek ethernet phy
drivers
Re-organize MediaTek ethernet phy driver files and get ready to integrate
some common functions (and add new 2.5G phy driver).
mtk-ge.c: MT7530 Gphy on MT7621 & MT7531 Gphy
mtk-ge-soc.c: Built-in Gphy on MT7981 & Built-in switch Gphy on MT7988
(mtk-2p5ge.c: Planned for built-in 2.5G phy on MT7988
--> in another patchset)
