[Severity: Low]
Is this vendor prefix redundant given the established thead prefix?

The kernel already relies heavily on the thead prefix for T-Head/XuanTie
processor IPs (like thead,c906, thead,th1520, and thead,c920). Adding
multiple vendor prefixes for the same company fragments the devicetree
namespace.

Also, since the actual compatible strings using this prefix were removed
in V2 (as noted in the changelog), the xuantie prefix is currently completely
unused. Would it be better to drop this patch entirely and continue using
the established thead prefix?
