Some Intel LPSS I2C devices make the SDA hold time and *CNT parameters available via SSCN (standard mode) and FMCN (fast mode) ACPI methods.
Implement support for this so that we check whether an ACPI method exists and if it does, fill in the SDA hold time and *CNT values to the device private structure for core to use.
