Cascading timers need to be enabled to count

[LunarLambda]

bool sioWait()
{
    // 50 ms timeout
    REG_TM0CNT = TIMER_FREQ_16KHZ;
    REG_TM0VAL = 65536 - 819;
    REG_TM1CNT = TIMER_FREQ_CASCADE;
    REG_TM1VAL = 0;
    REG_TM0CNT |= TIMER_ENABLE;

    while (!REG_TM1VAL);

    return hadTrans;
}

Had this code hang on hardware, despite working fine in mGBA. Turns out hardware demands the TIMER_ENABLE flag be set on both TM0 and TM1 for TM1 to count up.

This sounds like a simple oversight on my part.

I really should look for more of these TODOs in my code.
