drm/i915/bxt: Enable GMBUS IRQ
GMBUS interrupt has been moved to CPU side in BXT.
What this patch does is:
1. Enable GMBUS IRQ in de_post_install function
2. Handle this interrupt as a port interrupt in display irq
handler
v2: Rebase on top of the for_each_pipe() change adding dev_priv as
first argument (Damien).
v3: read BXT_DE_PORT_GMBUS IIR flag only on BXT on other platforms
it's reserved (imre)
v4: (jani)
- remove redundant 'BXT GMBUS' comment
- fix formatting of BXT_DE_PORT_GMBUS definition
