soc/intel/cannonlake: Steal no memory for disabled IGD
Set IgdDvmt50PreAlloc to zero if InternalGfx is disabled. It's 'correct' to do it like this, otherwise the FSP would always allocate memory for the IGD even if it is disabled. In addition the FSP enables the graphics panel power even if no IGD is present which leads to a crashing FSP. Thus, if no IGD is present we switch off the panel via UPDs. Refer to this issue on IntelFSP for details: https://github.com/IntelFsp/FSP/issues/49 Tested on: * CFL platform with IGD * CFL platform without IGD Change-Id: I6f9e0f9855224614471d8ed23bf2a9786386ddca Signed-off-by: Christian Walter <christian.walter@9elements.com> Reviewed-on: https://review.coreboot.org/c/coreboot/+/39454 Tested-by: build bot (Jenkins) <no-reply@coreboot.org> Reviewed-by: Angel Pons <th3fanbus@gmail.com> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Nico Huber <nico.h@gmx.de>
