Tomasz Bursztyka 48135cdd34 usermode: Rework Z_SYSCALL_SPECIFIC_DRIVER to fit with device refactoring 
init_fn is not anymore part of struct device, so let's test instead the
driver's API structure pointer which is also unique per device driver.

Tomasz Bursztyka 97326c0445 device: Fix structure attributes access 
Since struct devconfig was merged earlier into struct device, let's fix
accessing config_info, name, ... attributes everywhere via:

grep -rlZ 'dev->config->' | xargs -0 sed -i 's/dev->config->/dev->/g'

Peter A. Bigot e444274e95 drivers: counter: add Maxim DS3231 support 
The DS3231 is an I2C real-time clock with internal temperature
compensated oscillator, maintaining civil time to 1 s precision with
nominal 2 ppm accuracy from 0-40 Cel.

The basic functionality is exposed as a counter that is always running
at 1 Hz.  Much more functionality is exposed as driver-specific API,
including the ability to translate between the time scale of the DS3231
and the time scale of the Zephyr uptime clock.  This allows correlation
of events in the system clock to UTC, TAI, or whatever time scale is
used to maintain the DS3231.
