drivers: clock: rcar: Deploy a driver for each soc 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".

drivers: clock_control: add R-Car CPG MSSR driver Clock Pulse Generator, Module Standby Software Reset, are registers presents in Renesas Gen3 SoC series. MSSR is used to supply clock to the different modules, shuch as timer, or UART, it's also possible to issue a reset the different module. CPG registers allow to get the rate or to set some divider like for the CAN clock. Signed-off-by: Julien Massot <julien.massot@iot.bzh>

drivers: clock_control: Update drivers to use devicetree Kconfig symbol Update clock_control drivers to use DT_HAS_<compat>_ENABLED Kconfig symbol to expose the driver and enable it by default based on devicetree. We remove 'depend on' Kconfig for symbols that would be implied by the devicetree node existing. Signed-off-by: Kumar Gala <galak@kernel.org>
