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 648/660] net: mdio-i2c: add support for Clause 45 accesses
-
-Some SFP+ modules have PHYs on them just like SFP modules do, except
-they are Clause 45 PHYs.  The I2C protocol used to access them is
-modified slightly in order to send the device address and 16-bit
-register index.
