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.

This patch adds support for the v3020 RTC from EM Microelectronic.
The v3020 RTC is designed to be connected on a bus using only one data bit.
Since any data bit may be used, it is necessary to specify this to the
driver by passing a struct v3020_platform_data pointer (see
include/linux/rtc-v3020.h) to the driver.
Part of the following code comes from the kernel patchs produced by
Compulab for their products. The original file (available here:
http://raph.people.8d.com/misc/emv3020.c) was released under the terms of
the GPL license.
