[SRU] [I/OEM-5.13] [PATCH 2/7] thunderbolt: Make tb_port_type() take const parameter

[Kai-Heng Feng]

From: Mika Westerberg <mika.westerberg at linux.intel.com>

BugLink: https://bugs.launchpad.net/bugs/1941036

The function does not modify the object in any way so make the parameter
const to reflect this.

No functional changes intended.
