hardwaremain: explicitly call cbmem_initialize() early
Over the course of time there have been some implicit assumptions
about cbmem being available for find() or add() operations. However,
the cbmem area was never fully recovered until entering the state
machine: BS_ON_ENTRY into BS_PRE_DEVICE. Correct this assumption
by explicitly calling cbmem_initialize() in the EARLY_CBMEM_INIT
case.
This, however, doesn't fix timestamp_init() showing an error about
not being able to allocate the timestamp table.
