drm/i915: extend i915_vma_pin_iomap()

In the future display might try call this with a normal smem object,
which doesn't require PIN_MAPPABLE underneath in order to CPU map the
pages (unlike stolen).  Extend i915_vma_pin_iomap() to directly use
i915_gem_object_pin_map() for such cases.

This change was suggested by Chris P Wilson, that we pin
the smem with i915_gem_object_pin_map_unlocked().

v2 (jheikkil): Change i915_gem_object_pin_map_unlocked to
               i915_gem_object_pin_map
