thunderbolt: Correct TMU mode initialization from hardware
David reported that cppcheck found following possible copy & paste
error from tmu_mode_init():
tmu.c:385:50: style: Expression is always false because 'else if' condition matches previous condition at line 383. [multiCondition]
And indeed this is a bug. Fix it to use correct index
(TB_SWITCH_TMU_MODE_HIFI_UNI).
