x86: baytrail: pci region 3 is not always mapped to end of ram
Baytrail physically maps the first 2 GB of SDRAM from 0x0 to 0x7FFFFFFF
and additional SDRAM is mapped from 0x100000000 and up. There is a
physical memory hole from 0x80000000 to 0xFFFFFFFF for other uses.
Because of this, PCI region 3 should only try to use up to the amount of
SDRAM or 0x80000000, which ever is less.
