arch: arm: Add Analog Devices SC5xx machine type
Add support for the SC5xx machine type from Analog Devices. This
includes support for the SC57x, SC58x, SC59x, and SC59x-64 SoCs, which
have many common features such as common ADI IP blocks, and SHARC DSP
cores. This commit introduces core functionality required for all boards
using an SC5xx SoC, such as:
- SPL configuration
- Required CPU hooks such as reset
- Boot ROM interaction to load the stage 2 bootloader in the reference
configuration. Other options are possible but not officially supported
at this time
- SoC-common configuration expected to be reused by all boards
- Early initialization for system clocks and DDR controller
