[coreboot] [PATCH]make emulation/qemu-x86 slightly more standard

[Patrick Georgi]

Hi,

attached patch makes qemu use the udelay function in
src/pc80/udelay_io.c instead of the equivalent copy in
src/cpu/emulation/qemu-x86/northbridge.c.
Similar changes can be done for AMD boards (just with UDELAY_LAPIC), I
think.
