Shashank Sharma d04a492dd5 drm/i915/bxt: Add DDI hpd handler 
This patch adds a hot plug interrupt handler function for BXT.
What this function typically does is:
1. Check if hot plug is enabled from hot plug control register.
2. Call hpd_irq_handler with appropriate trigger to detect a
   plug storm and schedule a bottom half.
3. Clear sticky status bits in hot plug control register..

v2: (jani)
- drop redundant unlikely()
- s/Todo/FIXME:/ in code comment
- declare 'found' var in the scope where it's used
- check for IS_BROXTON before handling BXT_DE_PORT_HOTPLUG_MASK
