VT-d: reduce default verbosity
Introduce a new sub-option "verbose" to "iommu=", and hide most
(debugging) messages when that option is not specified. Particularly
messages printed after time management was initialized can, on
sufficiently large systems and with a graphical console, lead to
time management issues (therefore a call to process_pending_softirqs()
also gets added in case the new sub-option is being used).
While touching that code, also convert all improper uses of gdprintk()
to dprintk(), and convert all boolean iommu config variables to bool_t
residing in the .data.read_mostly section.
