vc/google: Show different logos for different ChromeOS devices

Browse Source 
This commit adds support for showing different logos on the ChromeOS
firmware splash screen based on the device model (between
Chromebook-Plus and regular ChromeOS devices like Chromebook and
Chromebox). This allows OEMs to customize the branding on their
devices.

This patch also introduces three new Kconfigs:
 - CHROMEOS_FW_SPLASH_SCREEN
 - CHROMEOS_LOGO_PATH
 - CHROMEBOOK_PLUS_LOGO_PATH
which allow users to enable the fw splash screen feature in the
vendorcode. Previously, we were using the BMP_LOGO Kconfig in
drivers/intel/fsp2_0, but we didn't want the top level Kconfigs to be
located inside the architecture specific files.

BUG=b:317880956
BRANCH=None
TEST=emerge-rex coreboot chromeos-bootimage
     verify that FW splash screen appears
