vboot: Change oprom checks to CONFIG_VBOOT, assert OPROM_MATTERS
Skipping display init on normal-mode boot is a vboot feature, not specific to Chrome OS. Fix the code in display_init_required() and pci_dev_init() to check CONFIG_VBOOT rather than CONFIG_CHROMEOS now that the two aren't always the same anymore. Also add a check to guarantee at compile time that CONFIG_VBOOT_OPROM_MATTERS is enabled on all platforms that make a check to this function (when CONFIG_VBOOT is also enabled). The whole display skipping mechanism is based on the oprom_needed NVRAM flag, and skipping display init without enabling the option to tell vboot that it needs to pay attention to that flag would make the whole thing not work right.
