Subject: [PATCH] i2c: davinci: use I2C_MAX_STANDARD_MODE_FREQ when no
 clock-frequency is set

Go for I2C_MAX_STANDARD_MODE_FREQ instead of a custom variant if no
clock-frequency property is set.

Besides, the calculation to kHz does not work for
DAVINCI_I2C_DEFAULT_BUS_FREQ as it is already specified in kHz.
