[ARM] rtc-pcf8583: Final fixes for this RTC on RiscPC
Replace the I2C bus address, as per drivers/acorn/char/pcf8583.c. Also, since this driver also contains Acorn RiscPC specific code for obtaining the current year from the SRAM (and updating the platform specific checksum when writing new data back) this is NOT a platform independent driver. Document it as such, and update the dependencies to reflect this fact. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

- If you say yes here you get support for the

+ If you say yes here you get support for the Philips PCF8583
+ RTC chip found on Acorn RiscPCs. This driver supports the
+ platform specific method of retrieving the current year from
+ the RTC's SRAM.
This driver can also be built as a module. If so, the module
will be called rtc-pcf8583.
