chromeos: vboot-related functions move to common vboot code

This moves a few vboot-prefixed functions that were defined in chromeos.c to
vboot_common.c, since those are only relevant to vboot and depend on the vboot
handoff data. This allows more separation between CONFIG_CHROMEOS and what
CONFIG_CHROMEOS selects, so that each separate option (such as
CONFIG_VBOOT_VERIFY_FIRMWARE) can be enabled separately.

Thus, the actual definitions of these functions will only be declared when
CONFIG_VBOOT_VERIFY_FIRMWARE is set, so the check before calling
vboot_skip_display_init in bootmode was also adapted.
