8916 has these
```
.ab_inefficiency = 100,
.ib_inefficiency = 200,
.clk_inefficiency = 105
```
which probably maps to:
```
 qcom,mdss-ab-factor = <1 1>;		/* 1 time    */
qcom,mdss-ib-factor = <2 1>;		/* 2 times  */
qcom,mdss-clk-factor = <105 100>;	/* 1.05 times */
```
8953 has same on mainline but these on ds:
```
qcom,mdss-ab-factor = <1 1>;		/* 1 time  */
qcom,mdss-ib-factor = <1 1>;		/* 1 time  */
qcom,mdss-clk-factor = <105 100>;	/* 1.05 times */
```
