dm: pci: Check board information pointer in decode_regions()
PCI enumeration may happen very early on an x86 board. The board
information pointer should have been checked in decode_regions()
as its space may not be allocated yet.
With this commit, Intel Galileo board boots again.
Fixes: 664758c ("pci: Fix decode regions for memory banks")
