Subject: [PATCH] rtc-ds1302: add some abstraction for new platform support

The current ds1302 driver (or at least the one that lives in /drivers/rtc)
seems to be designed for memory mapped devices only.  This make it quite
hard to add support for GPIO-based implementations (as this is the case
for the upcoming Arcom Vulcan).

This patch moves the direct register access to inline functions with
explicit names.  Still not as good as a proper platform driver, but at
least neater.
