Add Intel Tunnel Creek chipset support, mark it as tested

Intel's Tunnel Creek chipset supports both an SPI and an LPC bus. Set the
chipset table entry for Tunnel Creek to the new function
enable_flash_tunnelcreek(), which will read the hardware straps and return
support for the bus that has been used for booting. This function uses
ich_init_spi() with ich_generation set to 7 for initializing the SPI bus
if necessary.

SPI functionality tested on actual hardware, Tunnel Creek LPC interface not
tested yet (missing hardware for that).
