thunderbolt: Use correct type in tb_port_is_clx_enabled() prototype

tb_port_is_clx_enabled() generates a valid warning with gcc-13:
  drivers/thunderbolt/switch.c:1286:6: error: conflicting types for 'tb_port_is_clx_enabled' due to enum/integer mismatch; have 'bool(struct tb_port *, unsigned int)' ...
  drivers/thunderbolt/tb.h:1050:6: note: previous declaration of 'tb_port_is_clx_enabled' with type 'bool(struct tb_port *, enum tb_clx)' ...

I.e. the type of the 2nd parameter of tb_port_is_clx_enabled() in the
declaration is unsigned int, while the definition spells enum tb_clx.
Synchronize them to the former as the parameter is in fact a mask of the
enum values.
