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] crypto: caam - add functionality used by the caam_dma driver
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-The caam_dma is a memcpy DMA driver based on the DMA functionality of
-the CAAM hardware block. It creates a DMA channel for each JR of the
-CAAM. This patch adds functionality that is used by the caam_dma that is
-not yet part of the JR driver.
