Linux only needs access to the APSS DRV region, so the reg property should describe exactly one DRV region of size 0x10000. The example was using 0x30000 (three DRV regions) which is incorrect. Fix it to use 0x10000 to match the single APSS DRV region that the driver actually maps, consistent with the DT fixes applied across all platforms in this series.
