driver: clock: Add clock controller support in NPCX series. Add clock controller support for Nuvoton NPCX series. This CL includes: 1. Add clock controller device tree declarations. 2. Introduce clock-cells in yaml file clock tree to get module's source clock and turn off/on the its clock 3. Clock controller driver implementation. Signed-off-by: Mulin Chao <MLChao@nuvoton.com>

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>

Enable support for NPCX clock controller driver.
driver: clock: npcx: add a option to generate LFCLK via XTSOC This commit adds a new Kconfig option CLOCK_CONTROL_NPCX_EXTERNAL_SRC. With this option enabled, the internal 32.768 KHz clock (LFCLK) is generated by the on-chip Crystal Oscillator (XTOSC). Otherwise, the LFCLK is generated by the Low-Frequency Clock Generator (LFCG).

help
When this option is enabled, the internal 32.768 KHz clock (LFCLK)
is generated by the on-chip Crystal Oscillator (XTOSC).
This includes an on-chip oscillator, to which an external crystal
and the related passive components are connected.
