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] pci:add support aer/pme interrupts with none MSI/MSI-X/INTx
- mode
-
-On some platforms, root port doesn't support MSI/MSI-X/INTx in RC mode.
-When chip support the aer/pme interrupts with none MSI/MSI-X/INTx mode,
-maybe there is interrupt line for aer pme etc. Search the interrupt
-number in the fdt file. Then fixup the dev->irq with it.
