Add support for Falcon mode and explain in the README the steps to
boot the kernel directly without loading the full U-Boot.

mx6sabre boards can run different kernel versions, such as NXP 4.1 or
mainline.
Currently the rootfs location is passed via mmcblk number and the
problem with this approach is that the mmcblk number for the eMMC
changes depending on the kernel version.
In order to avoid such issue, use UUID method to specify the rootfs
location.
Succesfully tested booting a NXP 4.1 and also a mainline kernel on a
mx6qsabresd and mx6dlsabreauto.

WEIM cannot be used when I2C3 is enabled due to pin conflict, so keep
WEIM disabled by default.
I2C3 controls GPIO I2C expander (USB host and OTG have VBUS controlled by
the GPIO I2C expander), magnetometer, accelerometer.
Not disabling WEIM in U-Boot causes I2C3 to behave badly when booting
a NXP 4.1 kernel, which leads to probe failure on several devices,
including the lack of USB:
imx_usb 2184000.usb: Can't register ci_hdrc platform device, err=-517
By keeping WEIM disabled in U-Boot these kernel issues are gone.

As mx6sabreauto supports SPL now, all variants can boot using the same
defconfig.
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.
- Adds a README with instructions to build and flash SPL and u-boot.img.
