Enable cpufreq-dt support for da850-evm. The cvdd is supplied by the
tps6507 pmic with configurable output voltage, so all operating points
can be enabled.

I pulled part number for the processor used in the da850evm that Logic
PD produces, and it shows a imit of 375MHz.  I cross-referenced the
processor part number with the description from a distributor, and the
part number also lists 375MHz, so I think we should leave 456
disabled.
