drm: verisilicon: add max cursor size to HWDB

Different display controller variants support different maximum cursor
size. All known DC8200 variants support both 32x32 and 64x64, but some
DC8000 variants support either only 32x32 or up to 256x256.

The minimum size is fixed at 32 and only PoT square sizes are supported.

Add the max cursor size field to HWDB and fill all entries with 64.
