Use correct alternate function number for LED PWM on LPC
AF number was set to 2 for all LED outputs; however, on Mk.II, the
"Ready" and "Read" LEDs are connected to a different GPIO which has PWM
mapped to AF number 1.
Fix: wrong video mode in SuperCIC pair mode
In pair mode, CIC data lines are supposed to be outputs from the POV of the MCU.
During operation they could be switched back to inputs by the SysTick handler,
resetting the video mode/region back to NTSC regardless of settings.
