rtc: add support for ST M41T94 SPI RTC
This patch adds kernel driver for M41T94 RTC chip connected via SPI. I've tested it on two different AT91-based hardwares. This is third revision of the patch: some comments made by Alessandro Zummo fixed. Revision two added support for century bit and fixes. Signed-off-by: Kim B.
