This patch disables hotplug interrupts if an 'interrupt storm'
has been detected.
Noise on the interrupt line renders the hotplug interrupt useless:
each hotplug event causes the devices to be rescanned which will
will only increase the system load.
Thus disable the hotplug interrupts and fall back to periodic
device polling.
v2: Fixed cleanup typo.
v3: Fixed format issues, clarified a variable name,
changed pr_warn() to DRM_INFO() as suggested by
Jani Nikula <jani.nikula@linux.intel.com>.
