delta_get_board_type_name: use VHD fn

With VHD 6.3x and above, use VHD_BOARDTYPE_ToPrettyString() to support
also new types without having to manually manage the list, eg.:
- VHD_BOARDTYPE_MIXEDINTERFACE
- VHD_BOARDTYPE_FLEX_DEPRECATED
- VHD_BOARDTYPE_ASI
- VHD_BOARDTYPE_IP
- VHD_BOARDTYPE_HDMI20
- VHD_BOARDTYPE_FLEX_DP
- VHD_BOARDTYPE_FLEX_SDI
- VHD_BOARDTYPE_12G
- VHD_BOARDTYPE_FLEX_HMI
