ARM: dts: Enable additional GDSC collapse modes based on HW version

8974v2.2 supports additional collapse modes for Oxili, Venus,
and MDSS. Move the device-tree parameters that disable the modes
to version-specific files. Some MDSS collapse modes should still
remain disabled, even on v2.2.  All collapse modes are supported
on 8974Pro.
