[ARM] rtc-pcf8583: Final fixes for this RTC on RiscPC

Browse Source 
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.

If you say yes here you get support for the
Philips PCF8583 RTC chip.
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.
