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: phylink: make QSGMII a valid PHY mode for in-band AN
-
-QSGMII is a SerDes protocol clocked at 5 Gbaud (4 times higher than
-SGMII which is clocked at 1.25 Gbaud), with the same 8b/10b encoding and
-some extra symbols for synchronization. Logically it offers 4 SGMII
-interfaces multiplexed onto the same physical lanes. Each MAC PCS has
-its own in-band AN process with the system side of the QSGMII PHY, which
-is identical to the regular SGMII AN process.
-
-So allow QSGMII as a valid in-band AN mode, since it is no different
-from software perspective from regular SGMII.
