u-boot-zynq-uenv.bb: Add recipe to generate uEnv.txt environment

Add a recipe to generate uEnv.txt environments for SD boot of Zynq
targets. This replaces the existing uEnv.txt for zc702/zedboard that
were manually created and populated only for u-boot-xlnx builds.

The generated uEnv.txt files also support auto loading of the fpga
bitstream before the kernel.

Also enable the use of this recipe for all *-zynq7 machines that use
U-Boot and have SD/eMMC available. And additionally setup
IMAGE_BOOT_FILES for these machines.
