This change reworks how the linux-xlnx kernel is configured, instead of
using kmeta fragments as the base config the kernel is instead
configured with defconfigs from the vendor tree. This has been the
default for zcu102-zynqmp and now extends to Zynq and MicroBlaze
targets.
Since linux-yocto.inc is still included by the linux-xlnx.inc, it is
possible to still use kmeta like .scc/.cfg fragments separately as well
as from a kmeta source. This is used by default to get the KC705 and
ZYBO Linux-BD kernel configuration fragments. Though fragments are
limited to the current in layer provided fragments by default.
