  1. include/drivers: Add RTC API header and handlers 

    This commit adds the rtc.h header file which contains
API functions for real-time-clocks, which are low power
devices which track and represent broken-down time.

It also changes one line of doxygen documentation in the
maxim_ds3132.h file to place it in its own group.

The handlers for use of the API from userspace is also
added with this commit.

The API is split into one mandatory section, setting and
getting time, and three optional sections, alarms, update
event callback, and clock calibration.

  2. tests/drivers/rtc: Add unit tests for RTC devices 

    This test suite adds tests for the following:

- Setting and getting time
- Validating time is incrementing correctly
- Validating behavior of alarms with callback disabled
- Validating behavior of alarms with callback enabled
- Validating update callback

The test suite uses the devicetree  alias rtc to find
the device to test.

  3. boards/posix/native_posix: Add emulated RTC device driver 

    The emulated RTC device driver is used to emulate a real
RTC device. Note that it is not a replacement for the
native_rtc module, which is used to control simulated time,
get time from the host system, etc.

  5. tests/drivers/rtc: Add rtc_api_helpers test suite 

    This test suite validates the RTC API helper
functions, like currently, and exclusively, the
rtc_time_to_tm() helper function.

It also validates that the struct rtc_time is
member to member compatible with the struct tm
from the tm_sec to and including the tm_isdts
member.
