[PULL 16/34] aspeed: Add support for the tacoma-bmc board

[Peter Maydell <peter.maydell@linaro.org>]

From: Cédric Le Goater <clg@kaod.org>

The Tacoma BMC board is replacement board for the BMC of the OpenPOWER
Witherspoon system. It uses a AST2600 SoC instead of a AST2500 and the
I2C layout is the same as it controls the same main board. Used for HW
bringup.
