ARM: dts: enable rk808 dvs for rk3288 miniarm

Browse Source 
Buck1/2 can be controlled by gpio dvs, this is GPIO specifiers
for 2 host gpio's used for dvs. The format of the gpio specifier depends in
the gpio controller. If DVS GPIOs aren't present, voltage changes will happen
very quickly with no slow ramp time.
