Christian Walter b2f8ce7591 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
