AGESA: Use printk for IDS output

In all simplicity, with board/OptionsIds.h file having:
  IDSOPT_IDS_ENABLED TRUE
  IDSOPT_TRACING_ENABLED TRUE

And src/Kconfig modified to:
  config WARNINGS_ARE_ERRORS
  default n

With these settings AGESA outputs complete debugging log
where-ever you have your coreboot console configured.
