media: qcom: camss: Fix ordering of pm_runtime_enable
pm_runtime_enable() should happen prior to vfe_get() since vfe_get() calls
pm_runtime_resume_and_get().
This is a basic race condition that doesn't show up for most users so is
not widely reported. If you blacklist qcom-camss in modules.d and then
subsequently modprobe the module post-boot it is possible to reliably show
this error up.
The kernel log for this error looks like this:
qcom-camss ac5a000.camss: Failed to power up pipeline: -13
Fixes: 02afa816dbbf ("media: camss: Add basic runtime PM support")
