Revert "dix: Remove usage_hint from pixmaps, store it in ->drawable.class"

This reverts commit 1564c82417d201de5b9a5ec5e7aa4ef14c45fbad.

The drivers used the top bits of the usage_hint to store driver
private flags (intel, radeon, nouveau).

With EXA we need to get at this data so if we migrate the pixmap we
can create the correct type of pixmap in the driver, however this
commit truncates the usage_hint into 8-bit class and loses all the
good stuff.
