Some older SoCs use a deprecated MBUS binding with some clocks missing.
Currently, new SoCs must opt in to the complete binding. This should be
the default, so new SoCs do not accidentally use the deprecated version.

All of the sunxi SoCs since at least the A33 have a similar structure
for the MBUS and DRAM controller, but they all have minor differences in
MBUS port assignments and DRAM controller behavior. Give each SoC its
own compatible.

Shouldn't be compatibles introduced when they are actually used either in
driver or in DT file?

I have a question.
Are there the device drivers for the newly added compatible?

at least for D1, the MBUS node is used for U-Boot's DRAM driver.
