soc/intel/cannonlake: Set correct default sizes of Intel TXT memory

The CoffeeLake/CometLake requires the SINIT to be 320KB and the heap
of 960KB. The DPR should also be 4MB for these platforms. If these
regions are too small, the SINIT complains with error class 5 major
code 2 - insufficient HEAP size.

TEST=Boot Linux with tboot on Protectli VP4670 with TXT enabled.
