coreboot: dynamic cbmem requirement

Browse Source 
Dynamic cbmem is now a requirement for relocatable ramstage.
This patch replaces the reserve_* fields in the romstage_handoff
structure by using the dynamic cbmem library.

The haswell code is not moved over in this commit, but it should be
safe because there is a hard requirement for DYNAMIC_CBMEM when using
a reloctable ramstage.
