soc: qcom: qpnp-haptic: Optimize updating RATE_CFG registers

Currently, RATE_CFG registers are updated when the auto resonance
is enabled and no errors are seen with auto resonance or the play
rate is within allowed limits. However, it is getting updated
multiple times with the same play rate multiple times. This adds
up some delay in a critical path when the haptics duration is
small. While at it, add APIs to do multiple read/writes to the
peripheral registers like AUTO_RES_LO/HI and RATE_CFG1/2.
