Merge #150

150: Set mode correctly on C2 of 2-channel PWM r=newAM a=Gekkio

When configuring a 2-channel PWM and setting up channel 2 mode, we accidentally set up channel 1 mode instead.

I haven't actually verified the currently broken behaviour on hardware since I'm using 4-channel PWM where this configuration is done correctly, but this one looks like a simple copy-paste error which I spotted while studying the code 😅
