rS301972: siba(4): Adopt bcma-compatible mapping of bhnd(4) port/region identifiers.
Summary

For compatibility with bcma(4), map Sonics/OCP per-core address
spaces to bhnd(4) port/region identifiers as follows:

[port]	[addrspace]
device0.0	0
device1.0	1
device1.1	2
device1.2	3

This allows the use of common (port,region) address map identifiers
across both bus types.

Depends on D6849

Test Plan

Tested on:

  • BCM4312 (WiFi)
  • WGT634U (SoC)

With these changes, the WGT634U can successfully attach CFI flash
using the existing bcma(4)-compatible resource spec.

Tinderbox kernel build is pending.
