UefiPayloadPkg: Support variable size MMCONF space
The default size is still 256MiB, but will be overwritten by
UefiPayloadPkg with the real MMCONF size.
e.g.: On embedded AMD platforms the MMCONF window size is usually
only 64MiB.
Fixes crash on platforms not exposing 256 buses.
Tested on:
* AMD Stoney Ridge
