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] Change-Id: I25f07ac474b041358315530e5f391bb33d9c4d04 Signed-off-by: Matt DeVillier <matt.devillier@gmail.com> Reviewed-on: https://review.coreboot.org/17620 Tested-by: build bot (Jenkins) Reviewed-by: Martin Roth <martinroth@google.com> Reviewed-by: Paul Menzel <paulepanter@users.sourceforge.net> Reviewed-by: Prabal Saha <coolstarorganization@gmail.com>
