Summary

This is part of a series of PRs to add initial support for BLACKWOLF800BANW.

Other PRs in this series:

#850
#852
#853

This PR adds:

• platform_manager config: all i2c devices, ports spidev
• PlatformExplorer workaround to avoid i2c-i801 driver blocking platform_manager from claiming the idprom
• initial bsp_tests.json

Note: This PR depends on #774, where the SMB idprom and CHASSIS idprom are on the same idprom with different offsets.
