[PULL 09/29] aspeed: Deprecate the sonorapass-bmc machine

["Cédric Le Goater" <clg@redhat.com>]

The 'sonorapass-bmc' machine represents a lab server that never
entered production. There are no functional tests for this machine
which makes harder to determine when something becomes deprecated or
unused.

Since the machine does not rely on any specific device models, it can
be replaced by the 'ast2500-evb' machine using the 'fmc-model' option
to specify the flash type. The I2C devices connected to the board can
be defined via the QEMU command line.
