Support QEMU PIRQ routing via device tree on both i440fx and q35
platforms. With this commit, Linux booting on QEMU from U-Boot
has working ATA/SATA, USB and ethernet.

Writing 0xcb to I/O port 0xb2 (Advanced Power Management Control) causes
U-Boot to hang on QEMU q35 target. We introduce a config option in the
device tree "u-boot,no-apm-finalize" under /config node if we don't want
to do that.

Although the two qemu-x86 targets (i440fx and q35) share a lot in
common, they still have something that cannot easily handled in one
single device tree). Split to create two dedicated device tree files
and make the i440fx be the default build target.

As VGA option rom needs to run at C segment, although QEMU PAM emulation
seems to only guard E/F segments, for correctness, move VGA initialization
after PAM decode C/D/E/F segments.

Also since we already tested QEMU targets to differentiate I440FX and Q35
platforms, change to locate the VGA device via hardcoded b.d.f instead of
dynamic search for its vendor id & device id pair.

QEMU always decode legacy IDE I/O ports on PIIX chipset. However Linux ata_piix
driver does sanity check to see whether legacy ports decode is turned on.
To make Linux ata_piix driver happy, turn on the decode via IDE_TIMING register.

By default the legacy segments C/D/E/F do not decode to system RAM.
Turn on the decode via Programmable Attribute Map (PAM) registers
so that we can write configuration tables in the F segment.

PIRQ routing is pretty much common in Intel chipset. It has several
PIRQ links (normally 8) and corresponding registers (either in PCI
configuration space or memory-mapped IBASE) to configure the legacy
8259 IRQ vector mapping. Refactor current Queensbay PIRQ routing
support using device tree and move it to a common place, so that we
can easily add PIRQ routing support on a new platform.
