mx6sabreauto: Update to SPL only mode

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.

+How to use and build U-Boot on mx6sabreauto
+-------------------------------------------
+
+mx6sabreauto_defconfig target supports mx6q/mx6dl/mx6qp sabreauto variants.
+
+In order to build it:
+
+$ make mx6sabreauto_defconfig
+
+$ make

+
+$ sudo dd if=SPL of=/dev/sdX bs=1K seek=1 && sync
+
+- Flash the u-boot.img binary into the SD card:
+
+$ sudo dd if=u-boot.img of=/dev/sdX bs=1K seek=69 && sync
