If a ring is not initialized, it also should not be finished.
For example, in Vega10's SR-IOV environment, UVD's decode ring is not
initialized, but will be finnished in amdgpu_uvd_sw_fini, because UVD
driver put all the uvd decode ring's finish operation into
amdgpu_uvd_sw_fini function, while not uvd_vXXX_0_sw_fini. This will
lead to amdgpu module unloading failure.

the Pitcairn initialization silently falls through the Cape Verde

intentional, and the radeon driver doesn't have any such fallthrough,
so I suspect this is not supposed to happen.

As non-DT booting is no longer supported, the only way to instantiate
the device is through an OF node, which is guaranteed to be present.
Remove the unneeded check.

attribute_groups are not supposed to change at runtime. All functions
working with attribute_groups provided by <linux/sysfs.h> work with const
attribute_group. So mark the non-const structs as const.

The videomode structures are only copied into the vm field of a
panel_drv_data structure, so they can be const.

If the hpd_gpio is valid, use interrupt handler to react to HPD changes.
In case the hpd_gpio is not valid, try to enable hpd detection on the
encoder if it supports it.

The HPD signal can be used for detecting HDMI cable plug and unplug event
without the need for polling the status of the line.
This will speed up detecting such event because we do not need to wait for
the next poll event to notice the state change.

omap_framebuffer_create() fails to unref all the gem objects if creating
the FB fails, leading to a memory leak.
Fix the loop so that it goes through all the reffed gem objects.

Backmerge tag 'v4.13-rc5' into drm-next
Linux 4.13-rc5
There's a really nasty nouveau collision, hopefully someone can take a look
once I pushed this out.
