Subject: [PATCH V2] ARM: dts: imx6: correct anatop regulators range

According to i.MX6 datasheet, the LDO_1P1's typical
programming operating range is 1.0V to 1.2V, and
the LDO_2P5's typical programming operating range
is 2.25V to 2.75V, correct LDO_1P1 and LDO_2P5's
regulator range settings for i.MX6 SoCs.

changes since V1:
	Correct the regulator range according to datasheet's statement.
