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-17380-4 usb: host: xhci: add EH SINGLE_STEP_SET_FEATURE
- Test for USB2
-
-This function is similar with EHCI's, but implemented using XHCI.
-The USB2 host needs to send SETUP packet first, then wait 15
-seconds before DATA (IN) + STATUS stage.
-
-It is needed at USB Certification test for Embedded Host 2.0, and
-the detail is at CH6.4.1.1 of On-The-Go and Embedded Host Supplement
-to the USB Revision 2.0 Specification
