CONFIG_SYS_EARLY_PCI_INIT is not needed any more since with driver
model, PCI enumeration is automatically triggered.

Move chipset-specific codes such as PAM init, PCIe ECAM and MP table
from pci.c to qemu.c, to prepare for DM PCI conversion.

It looks that x86 chipset always contains a host bridge at pci
b.d.f 0.0.0, so enable this for all boards.

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.

The default weak version of pci_skip_dev() in drivers/pci/pci_common.c
skips the host bridge (b.d.f = 0.0.0) which is actually the i440fx/q35
chipset for QEMU targets. Define CONFIG_PCI_CONFIG_HOST_BRIDGE to make
it visible in the PCI configuration space.

It turns out that QEMU x86 emulated graphic card has a built-in
option ROM which can be run perfectly with native mode by U-Boot.

Some x86 boards set CONFIG_NR_DRAM_BANKS to 1, which causes incorrect
DRAM size printed when booting from coreboot, like this:

	CPU: x86, vendor Intel, device 663h
	DRAM:  636 KiB
	Using default environment

Change it to 8 which should be enough for both coreboot and bare
cases, and move it to x86-common.h.

This commit introduces the initial U-Boot support for QEMU x86 targets.
U-Boot can boot from coreboot as a payload, or directly without coreboot.
