Since commit d02be21d3004 ("i2c: imx_lpi2c: add ipg clk") getting
I2C clocks doesn't work. Add I2C IPG clock IDs to related switch
statements to fix it.

IPG clock description is missing for I2C0 and I2C2 busses,
add it. Otherwise we see -ENODATA error when trying to get
I2C clock for these busses.

I am wondering if we should just revert this commit instead?
