cpufreq: sun50i: add Allwinner H700 speed bin

Browse Source 
Support for the Allwinner H618, H618 and H700 was added to the sun50i
cpufreq-nvmem driver recently [1] however at the time some operating
points supported by the H700 (1.008, 1.032 and 1.512 GHz) and in use by
vendor BSPs were found to be unstable during testing, so the H700 speed
bin and  the 1.032 GHz OPP were not included in the mainline driver.

Retesting with kernel 6.10rc2 (which carries additional fixes for the
driver) now shows stable operation with these points.

Add the H700 speed bin to the driver.
