draw: use uint32_t instead of uint

In these cases we actually want uint32_t, because we're doing 32-bit
things to them.

The hwinfo-bit is only being used by i915, and should probably be
moved to i915 instead. But it shoukd *also* be converted, so let's do
that now.

While we're at it, fixup the bit-setting as well.
