Are you sure that there's no SRAM regulator on MT6572?

If there's none, there's no need to set sram_min_volt here, but if there is, you
also need to set sram_max_volt.

The ccifreq_supported explicitly set to false is ok for human readability of the
SoC features - that's also unneeded but keep it for the same of understanding
what's going on with this SoC.

Cheers,
Angelo
