hw/pci: partially handle pci master abort
A MemoryRegion with negative priority was created and
it spans over all the pci address space.
It "intercepts" the accesses to unassigned pci
address space and will follow the pci spec:
1. returns -1 on read
2. does nothing on write
Note: setting the RECEIVED MASTER ABORT bit in the STATUS register
of the device that initiated the transaction will be
implemented in another series
