haswell: use dynamic cbmem
Convert the existing haswell code to support reloctable ramstage
to use dynamic cbmem. This patch always selects DYNAMIC_CBMEM as
this option is a hard requirement for relocatable ramstage.
Aside from converting a few new API calls, a cbmem_top()
implementation is added which is defined to be at the begining of the
TSEG region. Also, use the dynamic cbmem library for allocating a
stack in ram for romstage after CAR is torn down.
Utilizing dynamic cbmem does mean that the cmem field in the gnvs
chromeos acpi table is now 0. Also, the memconsole driver in the kernel
won't be able to find the memconsole because the cbmem structure
changed.
