Intel Sunrisepoint (Skylake PCH) has the iTCO watchdog accessible across the SMBus, unlike previous generations of PCH/ICH where it was on the LPC bus. Because it's on the SMBus, it doesn't make sense to pass around a 'struct lpc_ich_info', and leaking the type of bus into the iTCO watchdog driver is kind of backwards anyway. This change introduces a new 'struct itco_wdt_platform_data' for use inside the iTCO watchdog driver and by the upcoming Intel Sunrisepoint code, which neatly avoids having to include lpc_ich headers in the i801 i2c driver. This change is overdue because lpc_ich_info has already found its way into other TCO watchdog users, notably the intel_pmc_ipc driver where the watchdog actually isn't on the LPC bus as far as I can see. A simple translation layer is provided for converting from the existing 'struct lpc_ich_info' inside the lpc_ich mfd driver.
