soc/intel/apollolake: Avoid hardcoding CAR region size for FSPM

Browse Source 
Instead of having to supply CAR memory region during compilation
time it is possible to determine it in runtime. FSP2.0 blobs carry
a copy of UPD structure pre-populated with 'default' values. The
default value for StackSize is actually the real value blob needs.
