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] dpaa_eth: fix iova handling for sg frames
-
-The driver relies on the no longer valid assumption that dma addresses
-(iovas) are identical to physical addressees and uses phys_to_virt() to
-make iova -> vaddr conversions. Fix this also for scatter-gather frames
-using the iova -> phys conversion function added in the previous patch.
-While at it, clean-up a redundant dpaa_bpid2pool() and pass the bp
-as parameter.
