Yangbo Lu cddd459140 layerscape: add patches-5.4
Add patches for linux-5.4. The patches are from NXP LSDK-20.04 release
which was tagged LSDK-20.04-V5.4.
https://source.codeaurora.org/external/qoriq/qoriq-components/linux/

For boards LS1021A-IOT, and Traverse-LS1043 which are not involved in
LSDK, port the dts patches from 4.14.

Subject: [PATCH] arm64: dts: lx2160aqds: Add mdio mux nodes
The two external MDIO buses used to communicate with phy devices that are
external to SOC are muxed in LX2160AQDS board.
These buses can be routed to any one of the eight IO slots on LX2160AQDS
board depending on value in fpga register 0x54.
Additionally the external MDIO1 is used to communicate to the onboard
RGMII phy devices.
The mdio1 is controlled by bits 4-7 of fpga register and mdio2 is
controlled by bits 4-7 of fpga register.
