i2c: qcom-geni: Support systems with 32MHz serial engine clock

In existing socs, I2C serial engine is sourced from XO (19.2MHz).
Where as in IPQ5424, I2C serial engine is sourced from GPLL0 (32MHz).

The existing map table is based on 19.2MHz. This patch incorporates
the clock map table to derive the SCL clock from the 32MHz source
clock frequency.
