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: bcm63xx_enet: move phy_(dis)connect into probe/remove
-
-Only connect/disconnect the phy during probe and remove, not during any
-open/close. The phy seldom changes during the runtime, and disconnecting
-the phy during close will prevent it from keeping any configuration over
-a down/up cycle.
