input: qcom-hv-haptics: add RC clock calibration for FIFO mode

As per the hardware documentation, adjust T_LRA using RC clock
calibration when playing in FIFO mode with play rate not less than
8 KHz. Based on the closed loop T_LRA, adjust the open loop T_LRA
specified in the device tree and use it in the calculation.
