After commit 8335d050bf24977afefee6612dd347abd555bc53 in pmbootstrap the
partition table now defaults to GPT instead of MBR. This breaks booting
on Amlogic devices for the following reasons:
* On set-top boxes: downstream U-Boot most likely does not have GPT
support
* On boards where we install mainline U-Boot as BL33 on eMMC/SD: the
bootROM checks for an `@AML` image header at offset 512 (second LBA),
which means we are basically stuck on MBR
Some Amlogic boards have U-Boot + the proprietary Amlogic firmware
stages in SPI flash (mainly the Libre Computer boards do), which means
they can use GPT, because the firmware is simply not stored on eMMC/SD.
For that reason I chose not to change the partition table on those.

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.
