configs/zynq_qmtech_defconfig: deprecate board

The zynq_qmtech_defconfig has not been maintained for 3 years, and is now
using a very out of date u-boot and Linux kernel.  Since there are 4 other
zynq7000 defconfigs available in buildroot and Julien no longer has a
functional board, drop the defconfig.
