soc/{baytrail/braswell/broadwell}: fix flashconsole on platform

Enabling flashconsole on these platforms fails to build due to
spi.c not being compiled in prior to ramstage. Include in early stages
(bootblock/romstage/postcar) as needed to enable flashconsole support.

Early inclusion of monotonic_timer.c is needed for Broadwell as well.
