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 01/11] MIPS: BCM63XX: add USB host clock enable delay
-
-Knowledge of the clock setup delay should remain at the clock level (so
-it can be clock specific and CPU specific). Add the 100 milliseconds
-required clock delay for the USB host clock when it gets enabled.
