msm: qpnp-haptic: add additional checks to avoid division by zero.
While calculating the +/-30% variation from the resonant frequency for auto
resonance search algorithm, division by zero is happening causing device
crash. Add additional checks to avoid such crashes. Also, RATE_CFG1 and
RATE_CFG2 registers should be updated with values from AUTO_RES_LO and
AUTO_RES_HI registers respectively only if the frequency variation is
+/-25% of the resonant freqeuncy. Add code change for the same.
