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 4/4] net: sfp: re-attempt probing for phy
-
-Some 1000BASE-T PHY modules take a while for the PHY to wake up.
-Retry the probe a number of times before deciding that the module has
-no PHY.
-
-Tested with:
- Sourcephotonics SPGBTXCNFC - PHY takes less than 50ms to respond.
- Champion One 1000SFPT - PHY takes about 200ms to respond.
- Mikrotik S-RJ01 - no PHY
