Convert SBI to use the intel_de_*() interface. This allows us to drop
the dependency in i915_drv.h while at it.
The fast timeout for the status wait drops from 100 us to 2 us on i915,
but that should be of no consequence. The slow timeout remains the same.

Future users of intel_de_wait_fw() need the final value. Just return it
for everyone using intel_wait_for_register_fw() and intel_de_wait_fw()
to avoid adding or using another set of specialized functions. There
aren't that many users for these anyway.
