Intel Tunnel Creek GPIO register block is compatible with current ich6-gpio driver, except the offset and content of GPIO block base address register in the LPC PCI configuration space are different. Use u16 instead of u32 to store the 16-bit I/O address of the GPIO registers so that it could support both Ivybridge and Tunnel Creek.
