ARM: dts: msm: enable LRA drive correction for haptics on pmi8998 and pm660
As per the hardware documentation, specify the following device
tree properties for pmi8998 and pm660.
- qcom,correct-lra-drive-freq
- qcom,misc-trim-error-rc19p2-clk-reg-present
These properties will ensure that LRA is driven at constant
resonant frequency under different operating conditions and
correct the frequency error (if any) in 19.2 MHz RC clock.
