sb/intel/lynxpoint: add missing I2C ACPI SSCN/FMCN methods
The SSCN and FMCN methods provide the optimal HCNT/LCNT timing values to
the driver, and are necessary when using I2C devices (eg, trackpad and
touchscreen) in ACPI (vs PCI) mode. Add these methods using the
timing values from Broadwell, which work for Haswell/Lynxpoint as well.
TEST: build google/peppy with trackpad/touchscreen devices in ACPI mode,
observe proper operation under Windows [8.1/10] and Linux [Mint 18]
