At some point the DPCD size was increased, but the debug print not. While
at it, switch to using hex dump.

The obvious downside here is that the hex dumping to buffer is done
regardless of drm.debug value. I thought it was still better than the
alternatives:
1) DRM_DEBUG_KMS with loads of %02x as it were
2) if (drm_debug & DRM_UT_KMS)
3) print_hex_dump(KERN_DEBUG, ... )
4) adding a new drm_print_hex_dump or similar that does 2) internally
