Certain devices, such as the Intel 82575GB, contain multiple nested
PCIe bridges (for example the PES12N3A). Coreboot does not set
the primary bus number of the lower bridges, causing upstream
forwarding failure. This in turn causes coreboot to fail to find
the lowest devices (in this case the NICs), and as a result the
required resources are not allocated and the NICs do not function.

To help hypervisors to assign PCI devices individually to virtualization
guests, page align dynamically allocated MMIO resources.
Tested with kontron/ktqm77 which has dynamically configured onboard
devices on the root bus and secondary buses. Booted Linux and checked
the configuration with `lspci -v`. Got the configuration through Muen's
tools which are very picky about overlapping and alignment. Booted a
Muen based system that uses many onboard devices. GMA, xHCI and one NIC
(on a secondary bus) were verified to function properly.

We also have static setting sysconf.segbit=0 which would conflict
with PCI_BUS_SEGN_BITS>0.
Having PCI_BUS_SEGN_BITS>0 would also require PCI MMCONF support

The PCI Specification states that devices that implement
a bridge and a secondary bus must swizzle (rotate) the
interrupt pins according to the table below:
Child Dev # Child PIN Parent PIN
0,4,8,12... A/B/C/D A/B/C/D
1,5,9,13... A/B/C/D B/C/D/A
2,6,10,14.. A/B/C/D C/D/A/B
3,7,11,15.. A/B/C/D D/A/B/C
Which is also described by this equation:
PIN_parent = (Pin_child + Dev_child) % 4
When a device is found and its bus number is greater than 0,
it is on a bridge and needs to be swizzled. Following the
string of parents up to the root bus and swizzling as we go
gives us the desired swizzling result. When BIOS_SPEW is
defined, it will print out each step of the swizzling process.

The main purpose of option rom is to supply int* handlers.
But supplying those is outside of coreboot scope and if someone needs those
they should run SeaBIOS anyway which runs the option roms wonderfully.
Running VGA oprom is kept because they're needed to init graphics.
This patch still keeps the options to include the option roms to make them
available to SeaBIOS.
