Subject: [PATCH] thunderbolt (gcc13): synchronize tb_port_is_clx_enabled()'s 2nd param

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 latter. And do the same for
tb_port_clx_supported() where the enum is propagated.
