The patch is to add support to make the output voltage of ACT8865
DC/DC regulator determined by VSET2[] bits. The DT property
"active-semi,vsel-high" is used to specify the VSEL pin at high
on the board. When the VSEL pin is high, output voltage is programmed
by VSET2[] bits.

regulator: act8865: add DT binding for property
"active-semi,vsel-high"

The DT property "active-semi,vsel-high" is used to specify the VSEL pin at high on the board.
