[1/5] wandboard: Fix detection for mx6q/mx6dl revD1 revariants

The detection of the revD1 version is based on the presence of the PMIC.

Currently revb1 device trees are used for mx6q/mx6dl variants, which
do not have the PMIC nodes.

This causes revD1 boards to be incorrectly be detected as revB1.

Use the revd1 device trees, so that the PMIC node can be found and
then the PMIC can be detected by reading its register ID.

Hi Heiko,

Could you please try this on your mx6dl wandboard revD1 board?

I recall you reported this issue sometime ago.

Derek tested this on his mx6q wandboard revD1 board and it worked
fine.

I have also tested it on a revB1 and the version is properly
detected.

Thanks

Sorry for sending this twice.

The first submission had the wrong patch 3/5.
