[Buildroot] [PATCH 2/2] configs: add Freescale SABRE Auto board support

SABRE Board for Automotive Infotainment (SABRE Auto, a.k.a. SABRE-AI) is
Freescale's evaluation board based on the i.MX 6 ARM Cortex-A9 applications
processor.

Those defconfigs are an adaptation of freescale_imx6{q,dl}sabresd_defconfig for
SABRE Auto, and are thus based on Freescale "official" git repo on
git.freescale.com and SW release 3.10.17_1.0.0_ga.

Hi,

I would like to "revive" a bit this proposal to add SABRE Auto defconfigs into
buildroot.

I have verified that all four freescale_imx6*sabre*_defconfig build properly,
and I could verify that the two freescale_imx6qsabre*_defconfig will boot from
SD card, using Luca's script.

Sadly, I cannot test that the two freescale_imx6dlsabre*_defconfig still run
correctly. Testers welcome! :)

Best regards,

V.


Changes since v1:

- Re-create from latest freescale_imx6{q,dl}sabresd_defconfig files.
