The linux-edge kernel enables the BL_SWITCHER kernel option, which enables
an in-kernel big.LITTLE switcher - with it enabled, only 4 cores are enabled
at a time, and the kernel switches between the big and little cores. However,
in a server workload, it's more likely that a user wants all 8 cores to work
simultaneously.
Disable the switcher by default by providing the no_bL_switcher cmdline option.
It can still be re-enabled by writing 1 to /sys/kernel/bL_switcher/active.

This cmdline argument is now a no-op. Drop it everywhere and add a new
CI check to enforce this.
Adjust the deprecated "minimal" initramfs variant to use
pmos.debug-shell to enable logging instead. It doesn't /support/
dropping to a shell, so the variable takes on a different meaning. But
that's ok since it's at least more consistent.

[ci:skip-build]: kernel builds are very likely to go through now
ODROID HC2 boards are out-of-use by the maintainer.
Move to testing and remove maintainer.

This devices runs a close-to mainline kernel as linux-odroid-hc2.
I have 2 of these devices which power my selfhosted infrastructure
for some time now and they work really well! Running my selfhosted
infrastructure on Alpine stable releases would be great.
The ODROID HC2 device must have its boot partition
on a microSD card while the rootfs can be on an external HDD.
Provide a script to transfer the rootfs and update the U-boot script.
