drm/i915: Decrease number of subplatform bits
Commit 6ce1c33d6c36 ("drm/i915: Kill INTEL_SUBPLATFORM_AML") removed the
only platform which used bit 2 so could also decrease the
INTEL_SUBPLATFORM_BITS definition.
This is not a fixes material but still lets make it precise.
v2:
* Fix assert in intel_device_info_subplatform_init by introducing
INTEL_SUBPLATFORM_MASK. (Chris)
* Update intel_subplatform().
