PNP: fix "work around Dell 1536/1546 BIOS MMCONFIG bug that breaks USB"

Initial stable commit : 2215d910

This patch backported into 2.6.32.55 is enabled when CONFIG_AMD_NB is set,
but this config option does not exist in 2.6.32, it was called CONFIG_K8_NB,
so the fix was never applied. Some other changes were needed to make it work.
first, the correct include file name was asm/k8.h and not asm/amd_nb.h, and
second, amd_get_mmconfig_range() is needed and was merged by previous patch.

Thanks to Jiri Slabi who reported the issue and diagnosed all the dependencies.
