drm/exynos: Add support for the nomodeset kernel parameter
According to disable Documentation/admin-guide/kernel-parameters.txt, this
parameter can be used to disable kernel modesetting.
DRM drivers will not perform display-mode changes or accelerated rendering
and only the system framebuffer will be available if it was set-up.
But only a few DRM drivers currently check for nomodeset, make this driver
to also support the command line parameter.
