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] MLK-17380-3 usb: move EH SINGLE_STEP_SET_FEATURE implement to
- core
-
-Since other USB 2.0 host may need it, like USB2 for XHCI. We move
-this design to HCD core.
