The I2C2 pins are already used and the following errors are seen:

imx27-pinctrl 10015000.iomuxc: pin MX27_PAD_I2C2_SDA already requested by 10012000.i2c; cannot claim for 1001d000.i2c imx27-pinctrl 10015000.iomuxc: pin-69 (1001d000.i2c) status -22 imx27-pinctrl 10015000.iomuxc: could not request pin 69 (MX27_PAD_I2C2_SDA) from group i2c2grp on device 10015000.iomuxc imx-i2c 1001d000.i2c: Error applying setting, reverse things back imx-i2c: probe of 1001d000.i2c failed with error -22

Fix it by adding the correct I2C1 IOMUX entries for the pinctrl_i2c1 group.
