Sorry, there was too much stuff commented so I preferred to clean up
all of them while maintaining the compatibles with the ralink prefix
instead since that was where the current discussion was at that point.

As I have said, this one exists:

arch/mips/ralink/mt7620.c:      rt_sysc_membase =
plat_of_remap_node("ralink,mt7620a-sysc");

I can change others to mediatek but that would be a bit weird, don't you think?
