MLK-14890 i2c: Enable I2C force idle bus

This patch enables the I2C force idle bus for all i.MX6 and i.MX7 boards to avoid
i2c bus problem during reboot. To use it, we must add some i2c properties in DTB file
and the GPIO pinctrl for i2c.

For mx6qsabreauto, mx6slevk, mx6sxsabresd and mx6sxscm, these boards call the
setup_i2c. To remove conflict, change to use "setup_i2c" only for non-DM i2c driver.
