The QN908x CPU has several timer modules: one RTC (Real-Time Clock) that can count from the 32kHz internal clock or 32.768 kHz external clock, four CTIMER that use the APB clock and have four channels each and one SCT timer with up to 10 channels running on the AHB clock. This patch implements a timer driver for the CTIMER blocks only, which is enough to make the xtimer module work. Future patches should improve on this module to support using the RTC CNT2 32-bit free-running counter unit and/or the SCT timer.
