kernel-module-mali is pulled in by libmali-xlnx:

  $ git grep -B1 kernel-module-mali
  .../libmali-xlnx.bb-RDEPENDS_${PN} = " \
  .../libmali-xlnx.bb:       kernel-module-mali \

Is libmali-xlnx built?

A few things to check, in top-bottom order:
 1. your machine conf should have something like
    PREFERRED_PROVIDER_virtual/libgles2 = "libmali-xlnx"
    PREFERRED_PROVIDER_virtual/egl      = "libmali-xlnx"
 2. libmali-xlnx should then be built
 3. libmali-xlnx RDEPENDS on kernel-module-mali, so it should
    be built as well

Bye,
