has working ATA/SATA, USB and ethernet.

5466983200 x86: qemu: Make host bridge (b.d.f=0.0.0) visible
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.

3d5bbbc471 x86: Set CONFIG_NR_DRAM_BANKS to 8 and move it to x86-common.h
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.
