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 2/7] gpio: thunderx: fix irq_request_resources
-
-If there are no parent resources do not call irq_chip_request_resources_parent
-at all as this will return an error.
-
-This resolves a regression where devices using a thunderx gpio as an interrupt
-would fail probing.
-
-Fixes: 0d04d0c ("gpio: thunderx: Use the default parent apis for {request,release}_resources")
