kernel: delete Linux 5.4 config and patches

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: connect to the fixed phy
-
-This patch is formed from 2 parts:
-   - first it moves the code that determines the if_mode to the
-     beginning so that it's used for both fixed link and phy mode.
-   - secondly, when in fixed link mode, call the phy_connect_phy
-     function as needed.
