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] net: mscc: ocelot: convert to use ocelot_get_txtstamp()
-
-The method getting TX timestamp by reading timestamp FIFO and
-matching skbs list is common for DSA Felix driver too.
-So move code out of ocelot_board.c, convert to use
-ocelot_get_txtstamp() function and export it.
