ARM: dts: imx6: phycore-som: fix arm and soc minimum voltage
The current set minimum voltage of 730000µV seems to be wrong. I don't
know the document which specifies that but the imx6qdl datasheets says
that the minimum voltage should be 0.925V for VDD_ARM (LDO bypassed,
lowest opp) and 1.15V for VDD_SOC (LDO bypassed, lowest opp).

Fixes: ddec5d1c0047 ("ARM: dts: imx6: Add initial support for phyCORE-i.MX 6 SOM")
