haswell: add multipurpose SMM memory region

Browse Source 
The SMM region is available for multipurpose use before the SMM
handler is relocated. Provide a configurable sized region in the
TSEG for use before the SMM handler is relocated. This feature is
implemented by making the reserved size a Kconfig option. Also
make the IED region a Kconfig option as well. Lastly add some sanity
checking on the Kconfig options.
