2c4e3ab117 bsps/shared: Fix bug in driver for I2C RTCs
The two RTCs supported by that driver (MCP7940M and EOZ9) use slightly
different register order. Add support for a different order to the
i2c-rtc driver.

3b053f6919 bsps/shared: Add Abracom EOZ9 RTC driver
The EOZ9 RTC has a similar register interface like the MCP7940M (and
quite some other I2C RTCs). This commit:

* Extracts the generic parts from MCP7940M and moves it into a generic
  i2c-rtc driver.
* Uses the new i2c-rtc for the MCP7940M.
* Uses the new i2c-rtc for the new Abracom EOZ9.

38dd86355d bsps/shared: Add MCP7940M RTC driver
The MCP7940M is a I2C RTC chip. The new driver uses the dev/i2c API to
support the RTC. It is written with the intention, that the driver can
be adapted to other RTCs with a similar register layout by just
replacing the initialization function.
