PATCH RESEND 2/2 MIPS: IP32: Add platform data hooks to use DS1685 driver

From: Joshua Kinard <[email protected]>

This modifies the IP32 (SGI O2) platform and reset code to utilize the new rtc-ds1685 driver. The old mc146818rtc.h header is removed and ip32_defconfig is updated as well.

Ralf,

Similar to Maciej's DEC/RTC patches from a few months ago, this patch
requires the rtc-ds1685 driver be added upstream first before this can go into into the LMO tree. If you can queue this someplace until that makes it in, that would be great. Thanks!
