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] net/phy: Inphi IN112525_s03 retimer updates
-
-The retimer doesn't get probed in linux due to the fact that it's a
-non-standard clause-45 device. Hardcoding the phyid in device-tree
-and adding custom routines for registry read/write operations
-solves the issue.
