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 Broadcom BCM84881 based SFPs work
-
-The Broadcom BCM84881 does not appear to send the SGMII control word
-when operating in SGMII mode, which causes network adapters to fail
-to link with the PHY, or decide to operate at fixed 1G speed, even if
-the PHY negotiated 100M.
-
-Work around this by detecting the Broadcom BCM84881 and switch to phy
-mode rather than inband mode.
