rS304859: [mips/broadcom] Generic platform_reset() support.

Summary

This adds support for performing platform_reset() on all supported
devices, using early boot enumeration of chipc capabilities and
available cores.

Changes:

Extended platform_reset() to support PMU, PMU+AOB, and non-PMU devices.
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).
Added Broadcom-specific MIPS CP0 register definitions used by BCM4785-specific reset handling.

Depends on D7498

Test Plan

Verified no regressions in reset handling on Asus RT-N16 and Netgear WGT634U.
Confirmed no regressions in bcma(4) bus enumeration on all supported SoC and WiFi chipsets.
Verified that reset now works correctly on Asus RT-N53, resolving the issue described in D6988.

If you both think it's fine, then I'm totally all for it going in :)
