avr32: Generic clockevents support
This combines three patches from David Brownell: * avr32: tclib support * avr32: simplify clocksources * avr32: Turn count/compare into a oneshot clockevent device Register both TC blocks (instead of just the first one) so that the AT32/AT91 tclib code will pick them up (instead of just the avr32-only PIT-style clocksource). Rename the first one and its resources appropriately. More cleanups to the cycle counter clocksource code - Disable all the weak symbol magic; remove the AVR32-only TCB-based clocksource code (source and header). - Mark the __init code properly. - Don't forget to report IRQF_TIMER. - Make the system work properly with this clocksource, by preventing use of the CPU "idle" sleep state in the idle loop when it's used. Package the avr32 count/compare timekeeping support as a oneshot clockevent device, so it supports NO_HZ and high res timers. This means it also supports plugging in other clockevent devices and clocksources.
