Add headers required for building PowerVR driver

The PowerVR driver on Qt for Embedded Linux needs to use Imagination
Techologies' proprietary pvr2d & wsegl APIs. These are the headers for
those APIs, allowing the powervr driver to be built. Ideally, these
headers would be provided as part of the SDK supplied by chipset vendors.
For now, we include these headers to let people get going with the
driver.

Licence headers were approved by legal for inclusion into Qt, after some
negotiation with ImgTec (who have also approved their inclusion into
Qt). The headers have also passed a scan by Talko, provided the licence
headers aren't touched.
