i2c: qcom-geni: update frequency table to fix timing parameters

Browse Source 
In IPQ5424, to meet the setup and hold timing requirements in the
standard mode, update the frequency table with the values recommended by
HW design team.

Also remove the stray space in the I2C_MAX_FAST_MODE_FREQ entry.

Fixes: 506bb2ab00 ("i2c: qcom-geni: Support systems with 32MHz serial engine clock")
