*-zynq7: Change some boards to mainline U-Boot by default

Change the microzed-zynq7, picozed-zynq7 and zybo-zynq7 machines to use
the mainline U-Boot by default.

All these machines can be supported by the mainline U-Boot and do not
require any of the drivers/features that are only provided in the Xilinx
vendor tree (u-boot-xlnx).
