[PATCH 2.6.27-rc4][RESEND] irq: irq and pci_ids patch for Intel Ibex Peak DeviceIDs

[Seth Heasley]

This patch updates the Intel Ibex Peak (PCH) LPC and SMBus Controller DeviceIDs.

The LPC Controller ID is set by Firmware within the range of 0x3b00-3b1f.  This range is included in pci_ids.h using min and max values, and irq.c now has code to handle the range (in lieu of 32 additions to a SWITCH statement).

The SMBus Controller ID is a fixed-value and will not change.
