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: ethernet: mtk_eth_soc: significantly reduce mdio bus
- access latency
-
-usleep_range often ends up sleeping much longer than the 10-20us provided
-as a range here. This causes significant latency in mdio bus acceses,
-which easily adds multiple seconds to the boot time on MT7621 when polling
-DSA slave ports.
-Use cond_resched instead of usleep_range, since the MDIO access does not
-take much time
