[PATCH v5 3/7] i2c: qcom-cci: Stop complaining about DT set clock rate

From: Bryan O'Donoghue <bryan.odonoghue@linaro.org>

It is common practice in the downstream and upstream CCI dt to set CCI
clock rates to 19.2 MHz. It appears to be fairly common for initial code to
set the CCI clock rate to 37.5 MHz.

Applying the widely used CCI clock rates from downstream ought not to cause
warning messages in the upstream kernel where our general policy is to
usually copy downstream hardware clock rates across the range of Qualcomm
drivers.

Drop the warning it is pervasive across CAMSS users but doesn't add any
information or warrant any changes to the DT to align the DT clock rate to
the bootloader clock rate.
