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] drm: bridge: cadence: Add support for periodically poll the
- connector
-
-Normally, DP/HDMI PHY use HPD_IRQ to monitor the connector connection
-status, but LS1028A doesn't support HPD_IRQ signals response.
-
-This patch allows periodically poll the connector for connection and
-disconnection.
