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.
