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] dpaa2-eth: Update FQ taildrop threshold and buffer pool count
-
-Now that we have congestion group taildrop configured at all
-times, we can afford to increase the frame queue taildrop
-threshold; this will ensure a better response when receiving
-bursts of large-sized frames.
-
-Also decouple the buffer pool count from the Rx FQ taildrop
-threshold, as above change would increase it too much. Instead,
-keep the old count as a hardcoded value.
-
-With the new limits, we try to ensure that:
-* we allow enough leeway for large frame bursts (by buffering
-enough of them in queues to avoid heavy dropping in case of
-bursty traffic, but when overall ingress bandwidth is manageable)
-* allow pending frames to be evenly spread between ingress FQs,
-regardless of frame size
-* avoid dropping frames due to the buffer pool being empty; this
-is not a bad behaviour per se, but system overall response is
-more linear and predictable when frames are dropped at frame
-queue/group level.
