drivers/thunderbolt: Enable NVM upgrade support on Intel Maple Ridge

Intel Maple Ridge supports NVM firmware upgrade with the same flows used on previous discrete Thunderbolt contollers from Intel (such as Titan Ridge). Advertise NVM upgrade support for Maple Ridge in icm_probe() to expose the corresponding files in /sys/bus/thunderbolt. The NVM firmware process was successfully tested on a system with a JHL8540 controller (ASUS ProArt Z790-CREATOR).
