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] usb: dwc3: use suspend clock from dt to set power down scale
-
-Since the new dwc3 use bulk clks including the suspend clk, so we can
-use it to calculate the power down scale value.
