Qualcomm PMIH010x PMIC has a haptics module inside and it could drive
a LRA actuator with several play modes, including: DIRECT_PLAY, FIFO,
PAT_MEM, SWR, etc. Add an initial driver to support two of the play
modes using the input force-feedback framework:

  -- FF_CONSTANT effect for DIRECT_PLAY mode which drives sinusoidual
    waveforms with fixed period and amplitude, which would generate
    a constant vibration effect on the LRA actuator.

  -- FF_PERIODIC effect with FF_CUSTOM for FIFO streaming mode, which
    can play an arbitrary waveform composed of a sequence of 8-bit
    samples at a configurable play rate.

Also, add the device node in the existing pmih0108 dtsi files, and enble
the haptics device for several boards by updating the vmax and
lra-period sttings according to the LRA components that mounted on each
of them.
