variants: WisMesh Tag: Enable DC/DC regulator

Browse source 
According to the documentation and experiments on other boards using
NRF52 + SX1262 this reduces the power consumption significantly. This
assumes that the hardware actually has the inductor for the internal
DC/DC regulator populated which is very likely. Even if not, it won't
hurt.
