As the upcoming release will be based on Linux 5.10 only, remove all
kernel configuration as well as patches for Linux 5.4.
There were no targets still actively using Linux 5.4.

-Subject: [PATCH] staging: fsl-dpaa2/mac: do not stop MAC when the net_dev is
- not up
-
-In case the net_device is not up, there is no need to call
-dpmac_mac_stop(). Guard the call by checking the IFF_UP flag.
-This patch will also solve the following warning generated by removing a
-dpmac that is not up.

-Also, remove the IFF_UP flag from the mac netdev since the PHY is not
-anymore started at probe time but is rather started/stopped on ifconfig
-up/down.
