Clean up dt binding descriptions and introduce titles where

from dt bindings, and needs succinct titles.

This commit introduces a driver for the Epson RX8130CE rtc.
The driver provides the following functionalities:
- Time setting and retrieval
- Periodic update interrupt support (1Hz)
- Alarm setting and retrieval (minute, hour, day)
- Frequency output control (32.768kHz, 1.024kHz, 1Hz, off)
- Power management (automatic power switching & battery charging)
- Calibration setting and retrieval

The Atmel SAM0 SoC enable peripherals clocks in distinct places: PM and
MCLK. The old devices had defined the peripheral clock enable bit at PM.
On the newer devices this was extracted on a dedicated memory section
called Master Clock (MCLK). This change excludes the dedicated bindings
in favor of a generic approach that cover all cases.
Now the clocks properties is complemented by the atmel,assigned-clocks
property. It gives the liberty to user to customize the clock source
from a generic clock or configure the direct connections.
All peripherals drivers were reworked with the newer solution.

Added NXP IRTC Driver support and binding.
This driver is expected for users needing
Time Date info in their application.
The driver additionally has an alarm mode that
can be enabled to fire an intterupt when the time
and alarm values match.

Adds support for settings/getting RTC time and using alarm/update feature.
The alarm option needs all fields to be set due to a hardware limitation.
RTC shares the same interrupt with the watchdog. Thus shared
interrupts must be enabled when WDT and RTC both need to trigger the ISR.

Set LPO 1KHZ clock for RTC if clock source 'LPO' is selected.
The frdm_ke17z512 has no 32KHZ OSC, the RTC clock comes from SOSC,
RTC_CLKIN, LPO 1KHZ. But usually the SOSC is connected with 8MHZ
oscilator, so only 1kHZ LPO is usable.
Update the nxp,kinetis-rtc.yaml to select RTC clock source.

Aligns the filename of TI's CC13/26xx system timer peripheral devicetree
binding to its compatible string.
Signed-off-by: Florian Grandel <fgrandel@code-for-humans.de>
This change introduces the "_rtc_timer" suffix for the system tick timer
driver "compatible" property and aligns naming conventions with the
actual CC13/26xx SoC series product policy.
This frees up the "_rtc" namespace to introduce additional APIs based on
the same peripheral in the future (not part of this PR):
rtc: rtc@... {
compatible = "ti,cc13xx-cc26xx-rtc";
...
timer {
compatible = "ti,cc13xx-cc26xx-rtc-timer";
...
};
counter {
compatible = "ti,cc13xx-cc26xx-rtc-counter";
...
};
pps {
compatible = "ti,cc13xx-cc26xx-rtc-pps";
...
};
};
Or alternatively an MFD pattern with similar requirements.
Fixing the namespacing now makes sense standalone as it reduces the
chance of custom drivers being broken in the future.
Redundant extension of the mandatory system clock devicetree node is
replaced with a single `status = "okay"` which seems to be the more
sensible default to avoid user error when defining custom boards.
Knowledgeable users can still override this if really needed.

Enabled RTC set/get time and alarm, alarm callback

Counter and RTC uses same hardware in case of
Motorola MC146818, so they can't be used at a time.
