[PATCH] drm/vc4: hdmi: Fix defined but not used warning

[Maxime Ripard]

On platforms without CONFIG_PM, SET_RUNTIME_PM_OPS will be a nop and the
functions vc4_hdmi_runtime_resume and vc4_hdmi_runtime_suspend will not
be used anywhere leading to

warning: 'vc4_hdmi_runtime_suspend' defined but not used [-Wunused-function]

Since we select CONFIG_PM anyway, vc4_hdmi_runtime_suspend() and
vc4_hdmi_runtime_suspend() will always be used and we can thus always
assign them in struct dev_pm_ops without using the SET_RUNTIME_PM_OPS
macro.

I'm not sure how to merge this one, since this commit has been reverted
in Linus tree, and un-reverted in linux-next. Should we wait a bit until
the reworked version of the original commit has been merged again?
