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] MLK-18898-1: ASoC: fsl_sai: select pinctrl state as function
- of bitclock rate
-
-Similar to DSD512 case we need a PCM pinctrl state option to map SAI BCLK
-to codec MCLK pin. Given that bitclock rate is function of slots number and
-slot width - pass bclk rate as parameter value from SAI driver.
