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] soc: fsl: dpio: change CENA regs to be cacheable
-
-Change cache enabled regsiter accessed to be cacheable
-plus non-shareable to meet the performance requirement.
-QMan's CENA region contains registers and structures that
-are 64byte in size and are inteneded to be accessed using a
-single 64 byte bus transaction, therefore this portal
-memory should be configured as cache-enabled. Also because
-the write allocate stash transcations of QBMan should be
-issued as cachable and non-coherent(non-sharable), we
-need to configure this region to be non-shareable.
