Add anatop regulators to imx6q.dtsi for all imx6q platforms.
I would expect all those regulator device nodes be sorted by register offset, and for the devices sharing the same register they can be sorted by anatop-vol-bit-shift.
I'm looking at the IMX6DQRM Rev. C, and commenting the differences I'm seeing from the document below.

Hi Shawn,
Sorry, why it is not 1.4V?
LDO 1p1 should be from range 0.8V to 1.4V on section 53.3.1

Hmm, I do not see 1.4V in register description (PMU_REG_1P1).
