[PATCH 1/3] ARM: dts: imx6: phycore-som: fix arm and soc minimum voltage

The current set minimum voltage of 730000mV seems to be wrong. I don't
know the document which specifies that but the imx6qdl datasheets says
that the minimum voltage should be 1.05V for VDD_ARM (LDO enabled, lowest
opp) and 1.275V for VDD_SOC (LDO enabled, lowest opp).
