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.

-
-Remove unnecessary show_state() in the loop inside
-i2c_pxa_pio_set_master(), which can be unnecessarily verbose.
-
-Remove the i2c_pxa_scream_blue_murder() in i2c_pxa_pio_xfer(), which
-will trigger if we are probing the I2C bus and a slave does not
-respond; this is a normal event, and not something to report.
