Convert jmr3927_clock_event_device to more generic txx9tmr_clock_event_device which supports one-shot mode. The txx9tmr_clock_event_device can be used for TX49 too if the cp0 timer interrupt was not available. Convert jmr3927_hpt_read to txx9_clocksource driver which does not depends jiffies anymore. The txx9_clocksource itself can be used for TX49, but normally TX49 uses higher precision clocksource_mips.
