platform: Restructure bmc_platform type

[ Upstream commit 9a830ee06c66058b1421c017b25a65a22921e9f6 ]

Segregate the BMC platform configuration into hardware and software
components. This allows population of platform default values for
hardware configuration that may no-longer be accessible by the host.
