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-15960-2: ASoC: fsl_sai: refine the pm runtime function
-
-In imx8qm/imx8qxp, the power domain of IP is enabled when
-pm_runtime_get_sync() is called, and disabled when pm_runtime
-_put_sync() is called. when power domain is disabled, the value
-of registers will lost, so we need to use the regcache_sync()
-to restore the registers in fsl_sai_runtime_resume.
