Subject[PATCH v2] ARM: imx: Enable cpuidle for i.MX6DL starting at 1.1
Date
Enable cpuidle support on i.MX6DL starting from IMX_CHIP_REVISION_1_1.

This also makes the code cleaner because 6q and 6dl actually have
different revision histories.

Changes since v1: https://www.spinics.net/lists/arm-kernel/msg610461.html
* Clarified comment but kept > instead of >= because that's what the
old code used. Would be OK to change with further feedback.
