configs: add Freescale i.MX6 SoloX Sabre SD support

The i.MX6 SoloX SABRE board for smart devices is Freescale's reference design
board based on the heterogeneous ARM Cortex-A9 + Cortex-M4 i.MX6 SoloX
applications processor.

This defconfig is inspired from previous freescale_imx6*sabresd_defconfig, and
is based on Freescale "official" git repo on git.freescale.com and SW release
3.10.53_1.1.0_ga.
