drm/i915/dsi: Replace poking of VLV GPIOs behind the driver's back
It's a dirty hack in the driver that pokes GPIO registers behind
the driver's back. Moreoever it might be problematic as simultaneous
I/O may hang the system, see the commit 40ecab551232 ("pinctrl:
baytrail: Really serialize all register accesses") for the details.
Taking all this into consideration replace the hack with proper
GPIO APIs being used.
