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 1/7] i2c: pxa: consolidate i2c_pxa_*xfer() implementations
-MIME-Version: 1.0

-Content-Transfer-Encoding: 8bit
-Content-Type: text/plain; charset="utf-8"
-
-Most of i2c_pxa_pio_xfer() and i2c_pxa_xfer() are identical; the only
-differences are that i2c_pxa_pio_xfer() may reset the bus, and they
-use different underlying transfer functions. The retry loop is the
-same. Consolidate these two functions.
