[PATCH] rtc-v3020: add ability to access v3020 chip with GPIOs

[Mike Rapoport <mike@compulab.co.il>]

The v3020 RTC can be connected to GPIOs as well as to memory-like interface.
Add ability to use GPIO bit-bang for v3020 read-write access.

The first patch in the serie is just coding style cleanup.
