Bug description:
  We need this patch for all Apollo Lake platforms for enabling the touchpad.
  This patch was cherry-picked from c50cdd62dda3f885c1e6ca8b3d5a0851c911ec54. And later backported to 4.4 kernel.
  It is because for Apollo Lake, the default freq/falling-time is incorrect. So it makes the i2c acts weird.

  Please consider SRU this commit.

  Impact:
    All touchpad on Apollo Lake work unstable on i2c mode. Sometimes it will      
    fallback to PS/2 mode and lost some functionality.                            
  Fix:
    touchpad works good on i2c mode.

  Tested:
    The patch is tested on many Dell ApolloLake laptops and works good.
