According to the TRM and downstream code from rockchip, the register
address of i2c1 on rk3368 is 0xff660000 and i2c2 is 0xff140000.

This patch fix the i2c1 & i2c2 register address definition error, also
fix the clk and pinctrl reference error.

after also checking the TRM for confirmation, applied to my dts64 branch


Thanks for catching that
