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] leds-bcm6328: support second hw blinking interval
-MIME-Version: 1.0
-Content-Type: text/plain; charset=UTF-8
-Content-Transfer-Encoding: 8bit
-
-Right now the driver uses only 3 LED modes:
-0: On
-1: HW Blinking (Interval 1)
-3: Off
-
-However, the controller supports a second HW blinking interval, which results
-in 4 possible LED modes:
-0: On
-1: HW Blinking (Interval 1)
-2: HW Blinking (Interval 2)
-3: Off
