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] enetc: Set MDIO_CFG_HOLD to the recommended value of 2
-
-This increases the MDIO hold time to 5 enet_clk cycles from the previous
-value of 0. This is actually the out-of-reset value, that the driver was
-previously overwriting with 0. Zero worked for the external MDIO, but
-breaks communication with the internal MDIO buses on which the PCS of
-ENETC SI's and Felix switch are found.
