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.
