Add support for capture events. Captured counter value for each channel can be retrieved through CCRx register. STM32 timers can have up to 4 capture channels (on input channel 1 to channel 4), hence need to check the number of channels before reading the capture data. The capture configuration is hard-coded to capture signals on both edges (non-inverted). Interrupts are used to report events independently for each channel.
