Hi Conor,

The sg2000/sg2002 SoCs have one A53 core which cv1812/cv1813 SoCs
don't have. I prefer sg2000/sg2002 are different chips, or at least
an enhanced version of existed cv1812/cv1813. It is not a simple
rename.

For this patch, the sg2000 doesn't need to disable A53 related clocks
like cv18xx series. So this compatible is needed to bind to this new
logic.

Thanks,
Inochi
