pvr: fix device info for GX6250 (4.45.2.58)

Synchronize GX6250 (4.45.2.58) device info with GX6250 (4.40.2.51) device info
and fill in the missing entries into GX6250 (4.45.2.58) device info . This is
important due to missing has_unified_store_depth , which leads to mesa warning:

```
MESA: warning: Missing unified_store_depth feature (defaulting to: 0U)
```
