  4. drivers: clock_control: stm32h7: Use dts based configuration macros 

    Update stm32h7 clock_control driver to make use of macros allowing
dts based configuration in coexistance with existing Kconfig method.

Note: Use of IS_ENABLED is removed as it generates warnings in
checkpatch. This checkpatch behavior needs to be reviewed but may
first require a little clean up of IS_ENABLED macro.

  6. board: nucleo_h745zi_q: Convert to dts based clock configuration 

    Configure board clocks using device tree.

Bus clocks configuration part is kept common to both cores.
On core dedicated configuration we find:
- Specific sysclock freq on both cores
- Sysclk input clock selection on M7 core only (as per existing
clock_control driver behavior).
