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] phy: usb: EHCI DMA may lose a burst of DMA data for 7255xA0
- family
-
-When the EHCI controller received a 512 byte USB packet that
-had to be broken into 2 256 byte bursts across the SCB bus AND
-there was a following 512 byte USB packet, the second burst of
-data from the first packet was sometimes being lost. If the
-burst size was changed to 128 bytes via the EBR_SCB_SIZE field
-in the USB_CTRL_EBRIDGE register we'd see the 4th 128 byte burst
-of the first packet being lost. This problem became much worse
-if other threads were running that accessed memory, like a memcpy
-test. Setting the EBR_SCB_SIZE to 512, which prevents breaking
-the EHCI USB packet (max size of 512 bytes) into bursts, fixed
-the problem.
