asm/mach/time.h is the ARM header file for setting up kernel ticker
timekeeping (be that the old jiffy interrupt or the new clocksource.)
RTC drivers have no business using this header file, and in fact do
not require it.
Build tested on at91sam9rl, omap and s3c2410 configurations.

Updates to the at91sam9 rtt-as-rtc driver:
- Bugfix: IRQ enable bits need shifting before masking with status
- Platform code to initialize wakeup bits didn't get merged; cope

AT91sam9 RTC support, primarily in the form of an RTT-as-RTC driver that was
extracted from 2.6.23-at91 patch and updated:
- Relies on now-merged platform updates, which associate the RTT
hardware address with each RTT and use the "at91_rtt" name.
- RTC framework related fixes and cleanups, notably:
* removed now-needless suspend/resume clock offset logic
* alarm read/write now respects the "enabled" flag
* suspend always disables update irqs
* shutdown (and startup) disables all irqs
- Misc cleanup:
* use dev_*() messaging
* add comments
* remove globals,
* ... etc
- Don't force use of RTT0 and GPBR0. Either resource may need
to be used for other purposes (like NO_HZ support).
- Update "AT91RM9200 RTC" Kconfig to allow it on SAM9RL chips
(it has both RTT and RTC).
Driver binding uses bus_find_device() to avoid needing any kind of "timer
library" code when there's more than one RTT module. (This timer can be used
as an RTC, to support NO_HZ operation, or potentially for other stuff. The
choice is a per-system policy.)
