Sorry, the description of the commit message is wrong.
I will change it to 
I3C SCL rate > 8MHz: use SDR0, as SDR1 has a maximum data rate of 8MHz
I3C SCL rate > 6MHz: use SDR1, as SDR2 has a maximum data rate of 8MHz
I3C SCL rate > 4MHz: use SDR2, as SDR3 has a maximum data rate of 8MHz
I3C SCL rate > 2MHz: use SDR3, as SDR4 has a maximum data rate of 8MHz
I3C SCL rate <= 2MHz: use SDR4
and send the v2 patch
