[Buildroot] [PATCH v2 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.

Changes since v1:

- Move erroneous mention of Sabre Auto from previous patch into this
  one.

- Add a "SABRE AUTO" section in the doc paragraph "Boot the SABRE
  board". Add a mention of the DB9 connector for the Sabre Auto debug
  UART.
