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] gpio/mpc8xxx: change irq handler from chained to normal
-
-More than one gpio controllers can share one interrupt, change the
-driver to request shared irq.
-
-While this will work, it will mess up userspace accounting of the number
-of interrupts per second in tools such as vmstat.  The reason is that
-for every GPIO interrupt, /proc/interrupts records the count against GIC
-interrupt 68 or 69, as well as the GPIO itself.  So, for every GPIO
-interrupt, the total number of interrupts that the system has seen
-increments by two.
