[PATCH v2] drm: ci: use clk_ignore_unused for apq8016

[Dmitry Baryshkov]

If the ADV7511 bridge driver is compiled as a module, while DRM_MSM is
built-in, the clk_disable_unused congests with the runtime PM handling
of the DSI PHY for the clk_prepare_lock(). This causes apq8016 runner to
fail without completing any jobs ([1]). Drop the BM_CMDLINE which
duplicate the command line from the .baremetal-igt-arm64 clause and
enforce the clk_ignore_unused kernelarg instead to make apq8016 runner
work.
