CBMEM: Always have early initialisation

Assume EARLY_CBMEM_INIT=y everywhere and remove option from Kconfig.

If romstage does not make the cbmem_initialize() call, features like
COLLECT_TIMESTAMPS and early CBMEM_CONSOLE will execute during
romstage, but that data will get lost as no CAR migration is
executed.
