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] staging: fsl_ppfe/eth: support single interface
- initialization
-
-- arrange members of struct mii_bus in sequence matching phy.h
-- if mdio node is defined, use of_mdiobus_register to register
-  child nodes (phy devices) available on the mdio bus.
-- remove of_phy_register_fixed_link from pfe_phy_init as it is being
-  handled in pfe_get_gemac_if_properties
-- remove mdio enabled check
-- skip phy init, if no PHY or fixed-link
