ARM: rockchip: Force CONFIG_PM on Rockchip systems

[ Upstream commit d1558dfd9f22c99a5b8e1354ad881ee40749da89 ]

A number of the Rockchip-specific drivers (IOMMU, display controllers)
are now assuming that CONFIG_PM is set, and may completely misbehave
if that's not the case.

Since there is hardly any reason for this configuration option not
to be selected anyway, let's require it (in the same way Tegra already
does).
