mfd: intel-lpss: Add default I2C device properties for Apollo Lake
Default I2C device properties for Intel Broxton, especially SDA hold time
may not be enough on Intel Apollo Lake. These properties are used in case
we don't get timing parameters from ACPI.
The default SDA hold time for Broxton may fail with arbitration lost errors
on Apollo Lake:
i2c_designware i2c_designware.1: i2c_dw_handle_tx_abort: lost arbitration
Fix this by using different default device properties on Apollo Lake than
Broxton.
