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.

The patches are sorted into the following categories:
  301-arch-xxxx
  302-dts-xxxx
  303-core-xxxx
  701-net-xxxx
  801-audio-xxxx

Subject: [PATCH] drivers/soc/fsl: add EPU FSM configuration for deep sleep
In the last stage of deep sleep, software will trigger a Finite
State Machine (FSM) to control the hardware procedure, such a
board isolation, killing PLLs, removing power, and so on.
When the system is waked up by an interrupt, the FSM controls
the hardware to complete the early resume procedure.
This patch configure the EPU FSM preparing for deep sleep.
