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] Sound: Soc: fsl: Set SAI Channel Mode to Output Mode
-
-Transmit data pins will output zero when slots are masked or channels
-are disabled. In CHMOD TDM mode, transmit data pins are tri-stated when
-slots are masked or channels are disabled. When data pins are tri-stated,
-there is noise on some channels when FS clock value is high and data is
-read while fsclk is transitioning from high to low.
