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: phy: vsc8514: enable in-band SGMII auto-negotiation
- setting
-
-The default in-band AN setting for the VSC8514 PHY is not very reliable:
-its out-of-reset state is with SerDes AN disabled, but certain boot
-firmware (such as U-Boot) enables it during the boot process.
-
-So its final state as seen by Linux depends on whether the U-Boot PHY
-driver has run or not.
-
-If SGMII auto-negotiation is enabled but not acknowledged by the MAC,
-the PHY does not pass traffic.
-
-But otherwise, it is able to pass traffic both with AN disabled, and
-with AN enabled.
-
-We would like to make this explicitly configurable rather than hardcoded
-as "on" as we are doing right now, but we'd rather hardcode it in LSDK
-and wait until a solution lands upstream, than invent a solution for
-this here.
