arm64: dts: qcom: sc7280: Adjust zombie PWM frequency

Browse Source 
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.
