ARM: dts: meson8b: add support for booting the secondary CPU cores
Booting the secondary CPU cores involves the following nodes/devices:
- SCU (Snoop-Control-Unit, for which we already have a DT node)
- a reset line for each CPU core, provided by the reset-controller
which is built into the clock-controller
- the PMU (power management unit) which controls the power of the CPU
cores
- a range in the SRAM specifically reserved for booting secondary CPU
cores
- the "enable-method" which activates booting the secondary CPU cores
This adds all required nodes and properties to boot the secondary CPU
cores.
