arm64: dts: qcom: sc7280: Adjust zombie PWM frequency
Tune the PWM to solve screen flashing issue and high frequency noise.
While at it, the comment for the PWM settings incorrectly said we were
using a 5kHz duty cycle. It should have said "period", not "duty cycle".
Correct this while updating the values.
