Hello Bora Guvendik, build bot (Jenkins), Anil Kumar K, Cliff Huang, Paul Menzel, Angel Pons, Arthur Heymans, Andrey Petrov, Zhixing Ma, Tarun Tuli, Nico Huber, Michał Żygowski, Subrata Banik, Nick Vaccaro, Boris Mittelberg,

drivers/intel/fsp2_0/memory_init: Inform user of memory training

If memory training is going to happen and early graphics is supported
by the mainboard, the `CONFIG_DISPLAY_MSG_DURING_MEMORY_TRAINING'
option makes coreboot display (on screen) the
`CONFIG_MEMORY_TRAINING_MSG' text message to inform the user that
memory training is in progress.

Memory training can take a while and an impatient end user facing a
black screen for a while may reset the device unnecessarily.
