[ARM] 5452/1: ep93x: rtc: use ioremap'ed addresses
Update the rtc-ep93xx driver to use ioremap'ed addresses. This removes the dependency on <mach/hardware.h> and properly reports the memory addresses used by the driver in /proc/iomem. In addition, ep93xx_rtc_init() is updated to use platform_driver_probe() instead of platform_driver_register(). Also, the device_create_file() calls are now properly checked for error conditions. The created sysfs files are also now removed when the driver is removed. The version number for the driver has been bumped at the request of Alessandro Zummo.
