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] PM: wakeup: Add routine to help fetch wakeup source object.
-
-Some user might want to go through all registered wakeup sources
-and doing things accordingly. For example, SoC PM driver might need to
-do HW programming to prevent powering down specific IP which wakeup
-source depending on. So add this API to help walk through all registered
-wakeup source objects on that list and return them one by one.
