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.

If pirq_routing_table points to NULL, that means U-Boot fails to

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.

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
