intel: Parse INTEL_NO_HW for devinfo construction

This commit does several things:

* Unify code common to several drivers by evaluating INTEL_NO_HW within
  intel_get_device_info_from_fd (suggested by Jordan).
* For drivers that keep a copy of the intel_device_info struct, a
  separate copy of the no_hw field is now unnecessary. Remove them.
* Minimize kernel queries when INTEL_NO_HW is true. This is done for
  code simplification, but we may find reason to undo this later on.
