MXSCM-292-2 mx6sxscm: convert to enable OF_CONTROL and DM drivers

Update mx6sxscm boards code and build configurations to enable
OF_CONTROL and DM drivers.

1. Update GPIO codes for adding gpio request
2. Update PMIC and LDO by-pass codes for DM PMIC
3. Add lpddr2 512MB size and eMMC options tolocal Kconfig
4. Update license with NXP 2017
5. Add defconfigs for EVB boards
