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] soc: fsl: add RCPM driver
-
-The NXP's QorIQ processors based on ARM Core have RCPM module
-(Run Control and Power Management), which performs system level
-tasks associated with power management such as wakeup source control.
-
-Note that this driver will not support PowerPC based QorIQ processors,
-and it depends on PM wakeup source framework which provide collect
-wake information.
