In the EFI config table, rename LINUX_EFI_SCREEN_INFO_TABLE_GUID to LINUX_EFI_PRIMARY_DISPLAY_TABLE_GUID. Read sysfb_primary_display from the entry. In addition to the screen_info, the entry now also contains EDID information. In libstub, replace struct screen_info with struct sysfb_display_info from the kernel's sysfb_primary_display and rename functions accordingly. Transfer it to the runtime kernel using the kernel's global state or the LINUX_EFI_PRIMARY_DISPLAY_TABLE_GUID config-table entry. With CONFIG_FIRMWARE_EDID=y, libstub now transfers the GOP device's EDID information to the kernel. If CONFIG_FIRMWARE_EDID=n, EDID information is disabled. Make the Kconfig symbol CONFIG_FIRMWARE_EDID available with EFI. Setting the value to 'n' disables EDID support. Also rename screen_info.c to primary_display.c and adapt the contained comment according to the changes.
