CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT is not the correct method
to set I/O to 1.8. To boards that does not support vqmmc-supply,
use vs18_enable in fsl_esdhc_cfg. If regulator is supported,
use fixed 1.8V regulator for vqmmc-supply.

Handle vqmmc supply. Some boards have a fixed I/O voltage
at 1.8V for emmc, so the usdhc also needs to be configured
as 1.8V by setting VSELECT bit. The vs18_enable is the one
that used to checking whether setting VSELECT or not in
the driver. So if vqmmc supply is 1.8V, set vs18_enable,
the driver will set VSELECT.

When using eMMC with 1.8V I/O, the VSELECT bit need to be set in
the USDHC controller when init.
This patch adds a parameter "vs18_enable" in fsl_esdhc_cfg
structure and priv data, so each controller can have different
settings.
We could not use CONFIG_SYS_FSL_ESDHC_FORCE_VSELECT, it has problem
that it will apply to all USDHC controllers and it only set the 1.8V
at init phase. So if user does not select to the eMMC device,
the voltage on the I/O pins are not correct.

This patch:
- Removes non-SPL targets.
- Renames target to mx6sabreauto_defconfig.
- Renames folder and board files to mx6sabreauto.
- Updates MAINTAINERS, Makefile and Kconfig accordingly.
- Removes .cfg files.

When CONFIG_DM_ETH is set, the FEC ethernet controller is reset after

DTB is encoded in big endian. When we retrieve property values,
we need to use fdt32_to_cpu (aka be32_to_cpu) for endian conversion.
This is a bit error-prone, but sparse is useful to detect endian
mismatch.
We need to use (fdt32_t *) instead of (u32 *) for a pointer of a
property value. Otherwise sparse warns "cast to restricted __be32".
