ARM: omap: fix uninformative vc/i2c configuration error message
On my OMAP4 platform, I'm getting this error message repeated several times at boot: omap_vc_i2c_init: I2C config for all channels must match. omap_vc_i2c_init: I2C config for all channels must match. This doesn't help identify what the problem is. Fix this message to be more informative: omap_vc_i2c_init: I2C config for vdd_iva does not match other channels (0). omap_vc_i2c_init: I2C config for vdd_mpu does not match other channels (0). This allows us to identify which voltage domains have a problem, and what the I2C configuration state (a boolean, i2c_high_speed) setting being used actually is. From this we find that omap4_core_pmic has i2c_high_speed false, but omap4_iva_pmic and omap4_mpu_pmic both have it set true.
