drm/i915: Tune down spurious CRC interrupt warning

We don't really synchronously turn them off from debugfs. We try to
avoid hitting them too badly by waiting one vblank, but apparently the
irq handler can still race through that gap.

Since this isn't really all that important for testcases, only for

drm/i915: Handle runtime pm in the CRC setup code

The crc code doesn't handle anything really that could drop the
register state (by design so that we have less complexity). Which
means userspace may only start crc capture once the pipe is fully set
up.

With an i-g-t patch this will be the case, but there's still the
problem that this results in obscure unclaimed register write
failures. Which is a pain to debug.

So instead make sure we don't have the basic unclaimed register write
failure by grabbing runtime pm references. And reject completely
invalid requests with -EIO. This is still racy of course, but for a
test library we don't really care - if userspace shuts down the pipe
right afterwards the entire setup will be lost anyway.

v2: Put instead of get, spotted by Damien. Also explain the runtime pm
dance.

v3: There's really no need for rpm get/put since power_is_enabled only
checks software state (Damien).

Furthermore we don't even enable these interrupts any more on gen5+
(though the handling code is still there). So this mostly concerns old
platforms.
