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 09/11] MIPS: BCM63XX: add support for the on-chip EHCI
- controller
-
-Broadcom BCM63XX SoCs include an on-chip EHCI controller which can be
-driven by the generic ehci-platform driver by using specific power
-on/off/suspend callbacks to manage clocks and hardware specific
-configuration.
