When adding support for V3U (r8a779a0) it was incorrectly recorded it supports four nodes, while in fact it supports five. The fifth node is named TSC0 and breaks the existing naming schema starting at 1. Work around this by separately defining the reg property for V3U and others. Restore the maximum number of nodes to three for other compatibles as it was before erroneously increasing it for V3U.
