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-21484-4: ASoC: fsl_sai: ensure clk not in use prior
- set_mclk_rate
-
-On recent kernels clks which are marked with CLK_SET_RATE_GATE are
-"protected" against further changes at clk_prepare time, including clk
-set_parent and set_rate. See commit 9461f7b33d11 ("clk: fix
-CLK_SET_RATE_GATE with clock rate protection"). The current fsl_sai
-implementation ensures the clock is not in use prior set_parent,
-extend this for set_rate also by moving if (sai->mclk_streams == 0)
-outside fsl_sai_set_mclk_rate(). Aside of this avoid changing rate and
-parent for BUS clk.
