This patch lays the groundwork for switching sun4u over from ioport NVRAM access to MMIO NVRAM access.
Patch 1 introduces a new year_offset property which is the offset between the year value stored in hardware and the actual year. In particular, Sun hardware has a 68 year offset used to extend the date range of the IC. While the kernel sources I have viewed contain this offset within a #ifdef CONFIG_SPARC block, I've updated all the callers so that no change in behaviour will be seen across all platforms. PPC users may wish to alter the callers to change this behaviour as required. Patch 2 adds a new m48t59 sysbus device in preparation for use with sun4u in a subsequent patch.
