This adds support for performing platform_reset() on all supported devices, using early boot enumeration of chipc capabilities and available cores. - Added Broadcom-specific MIPS CP0 register definitions used by BCM4785-specific reset handling. - Added a bcm_platform structure for tracking chipc/pmu/cfe platform data. - Extended the BCMA EROM API to support early boot lookup of core info (including port/region mappings). - Extended platform_reset() to support PMU, PMU+AOB, and non-PMU devices.
