[Qemu-devel] [PATCH 1/2 v2] pci: change default value of rom_bar to 2

[Bandan Das <bsd@redhat.com>]

The following patch depends on the value of rom_bar to
determine rom blacklist behavior. Existing code shouldn't
be affected by changing the default value of rom_bar since
all relevant decisions only rely on whether rom_bar is zero
or non-zero.
