device: provide option to always load PCI option roms

Certain kernel drivers require the presence of option rom
contents because the board's static configuration information
is located within the blob. Therefore, allow a chipset/board to
instruct the pci device handling code to always load but not
necessarily run the option rom.

BUG=chrome-os-partner:25885
BRANCH=baytrail
TEST=Both enabling and not enabling this option shows expected behavior.

ChromeOS: Remove oprom_is_loaded

A global flag oprom_is_loaded was used to indicate to
U-boot that VGA option ROM was loaded and run, or that
native VGA init was completed on GMA device.

Implement this feature without dependency to CHROMEOS option
and replace use of global variable oprom_is_loaded with call
to gfx_get_init_done().

device: Conditionally bypass oprom execution

Builds with CHROMEOS can bypass VGA oprom when boot is not in
developer or recovery modes. Have the same functionality available
without CHROMEOS but with BOOTMODE_STRAPS.
