rtc: add rtc-m41t80 driver

This is a new-style i2c driver for ST M41T80 series RTC chip, derived from
works by Alexander Bigga <ab@mycable.de> who wrote the original
rtc-m41txx.c based on drivers/i2c/chips/m41t00.c driver.

This driver supports M41T8[0-4] and M41ST8[457].  The old m41t00 driver
supports M41T00, M41T81 and M41T85(M41ST85).  While the M41T00 chip is now
supported by rtc-ds1307 driver, this driver does not include support for
the chip.

If you say Y here you will get support for the
ST M41T80 RTC chips series. Currently following chips are
supported: M41T80, M41T81, M41T82, M41T83, M41ST84, M41ST85
and M41ST87.
This driver can also be built as a module. If so, the module
will be called rtc-m41t80.
