drm/i915/dsi: Replace poking of CHV 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 0bd50d719b00 ("pinctrl:
cherryview: prevent concurrent access to GPIO controllers") for
the details. Taking all this into consideration replace the hack
with proper GPIO APIs being used.
