Description

Now that ChibiOS has been updated, we can use GPT timers to emulate Using hardware timer 1 with software PWM without using the TIM1-4 PWM timers. Binding backlight to an out the way timer avoids conflicts with other features such as PWM ws2812 and allows for a more performant default behaviour for CTPC.

Next phase could be to migrate BACKLIGHT_PWM_TIMER from the avr backlight code.

Works fine once I include the extra header.

Retargeted to develop -- conflicting file now lives at platforms/chibios/GENERIC_STM32_F303XC/configs/mcuconf.h.
