[PATCH v2 4/8] drm: adv7511: Add supply_names and num_supplies variables to struct adv7511_chip_info

[Biju Das <biju.das.jz@xxxxxxxxxxxxxx>]

The ADV7511 has 5 power supplies compared to 7 that of ADV75{33,35}. Add
supply_names and num_supplies variables to struct adv7511_chip_info to
handle this difference.

v1->v2:
 * Added Rb tag from Laurent.
 * Added trailing commas for num_supplies in adv753{3,5}_chip_info.
