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 01/17] i2c: pxa: use official address byte helper
-MIME-Version: 1.0
-Content-Disposition: inline
-Content-Transfer-Encoding: 8bit
-Content-Type: text/plain; charset="utf-8"
-
-i2c-pxa was created before i2c_8bit_addr_from_msg() was implemented,
-and used its own i2c_pxa_addr_byte() which is functionally the same.
-Sadly, it was never updated to use this new helper. Switch it over.
