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: dsa: felix: Fix CPU port assignment when not last port
-
-On the NXP LS1028A, there are 2 Ethernet links between the Felix switch
-and the ENETC:
-- eno2 <-> swp4, at 2.5G
-- eno3 <-> swp5, at 1G
-
-Only one of the above Ethernet port pairs can act as a DSA link for
-tagging.
-
-When adding initial support for the driver, it was tested only on the 1G
-eno3 <-> swp5 interface, due to the necessity of using PHYLIB initially
-(which treats fixed-link interfaces as emulated C22 PHYs, so it doesn't
-support fixed-link speeds higher than 1G).
-
-After making PHYLINK work, it appears that swp4 still can't act as CPU
-port. So it looks like ocelot_set_cpu_port was being called for swp4,
-but then it was called again for swp5, overwriting the CPU port assigned
-in the DT.
-
-It appears that when you call dsa_upstream_port for a port that is not
-defined in the device tree (such as swp5 when using swp4 as CPU port),
-its dp->cpu_dp pointer is not initialized by dsa_tree_setup_default_cpu,
-and this trips up the following condition in dsa_upstream_port:
-
-	if (!cpu_dp)
-		return port;
-
-So the moral of the story is: don't call dsa_upstream_port for a port
-that is not defined in the device tree, and therefore its dsa_port
-structure is not completely initialized (ds->num_ports is still 6).
-
-Fixes: 56051948773e ("net: dsa: ocelot: add driver for Felix switch family")
