mfd: intel-lpss: Add default I2C device properties for Gemini Lake
commit3f31bc67e4
upstream. It turned out Intel Gemini Lake doesn't use the same I2C timing parameters as Broxton. I got confirmation from the Windows team that Gemini Lake systems should use updated timing parameters that differ from those used in Broxton based systems. Fixes:f80e78aa11
