The global variable edid_info contains the firmware's EDID information
as an extension to the regular screen_info on x86. Therefore move it to
<asm/screen_info.h>.

Add the Kconfig token ARCH_HAS_EDID_INFO to guard against access on
architectures that don't provide edid_info. Select it on x86.

I'm not sure we need another symbol in addition to
CONFIG_FIRMWARE_EDID. Since all the code behind that
existing symbol is also x86 specific, would it be enough
to just add either 'depends on X86' or 'depends on X86 ||
COMPILE_TEST' there?
