phy: tegra: Remote self cast in tegra_xusb_port_find_lane

Clang warns about casting variables to themselves because it is rarely necessary. Removing the cast should not change anything regarding the code and silences the warning.

../drivers/phy/tegra/xusb.c:421:11: warning: explicitly assigning value of variable of type 'const struct tegra_xusb_lane_map *' to itself [-Wself-assign]

        for (map = map; map->type; map++) {
             ~~~ ^ ~~~

I am not entirely sure if this is the correct solution, especially since I don't have the hardware and I am not too familiar with this code. If there is a better solution, please let me know.
