Mitsuru IWASAKI 2bfb7205bf Add Timer device driver for power management events.
The code for suspend/resume is derived from APM device driver.

Some people suggested the original code is somewhat buggy, but I'd
like to just move it from apm.c without any major changes for the
initial version.  This code should be refined later.

To use pmtimer to adjust time at resume time, add
	device	pmtimer
in your kernel config file, and add
	hint.pmtimer.0.at="isa"
in your device.hints
