Define a single node that reflects the LCDC IP. Instead of defining
the same IP block twice with different compatibles (mipi dbi, display)
we define a single node for the default display interface and
other interfaces like the MIPI DBI should override the compatible entry
with the appropriate one within its DTS overlay file.

r8a779f0 is also know as S4, this SoC is part of the Gen4 SoC series,
has 8 Cortex-A55 and a dual core lockstep Cortex-R52 processor.
SCIF0 is dedicated to Zephyr and SCIF3 to Linux.
**Control Domains**
IMPORTANT: This SoC is divided into two "domains":
- Application domain contains some peripherals as well as A55 & R52 cores.
- Control domain that contain a G4MH/RH850 MCU and other peripherals.
In order to access control domain peripherals such as gpio4-7 and CAN-FD
from application domain, the G4MH MCU has to unlock a protection
mechanism from control domain buses.
"Protected" controllers will be flagged in gen4 device trees,
warning users that they need to flash a custom G4MH firmware
to unlock access to these controllers.
**Clock controller**
This SoC clock controller is offering "domains"
for each world (Zephyr/Linux).
These domains are several "entry points" to the clock controller
which are arbitrated to avoid a world from turning off a clock needed
by another one.
We decided to use the same domain as Linux because the
security mechanism as to be implemented before accessing
another domain.

Renesas Renesas SmartBond(tm) have two ADC blocks:
GPADC and SDADC.
This change adds drivers for both.
Each ADC supports only one channel setup, drivers allow
to have multiply channels in sequence. Switching
between ADC sources in done in software.
GPADC has 10 bit resolution (accuracy can be increase
with oversampling). Values up to 3.6V can be measured
on selected pins. V30 and VBAT1 can also be measured.
SDADC has 14 bit resolution and can take measurements
from 8 pins (single of differential) and VBAT.

This commit rewrite renesas R-Car clock driver in order
to be able to support any new SoC easier.
This work is so creating a clock driver per soc alongside a
common driver for all reneasas r-car boars.
- drivers: create a driver per soc
- create a common driver
- create a common header used by soc & common driver
- create a soc specific driver calling for common driver
- dts: use new compatible
- use old yaml as common yaml
- create a new "child" yaml to define the new compatible field
- change compatible in device tree
As in Linux, the driver can support both r8a77951 and r8a77950
SoC's so we decided to name the new driver as in Linux with Zephyr
prefix : "clock_control_r8a7795_cpg_mssr.c".

This commit is reworking clock definition in

as much as possible.
- dt-bindings: rework renesas clocks dt-bindings
- regroup renesas related dt-bindings in a folder
- rename renesas rcar common dt-binding to match linux name
- add soc specific dt-binding matching linux name
- soc dt-bindings are defining clocks matching linux names
- dts: use new clocks names
- move clocks definitions in SoC layer for each core clock entry
- driver: use new clocks names
As seen in this commit, we are declaring clocks for "R8A7795" SoC
to match linux names.
Linux is not declaring "R8A77951" SoC specific files because
its also supporting the first H3 SoC version numbered "R8A77950".
