input: misc: Add initial driver to support QTI HV haptics

Browse Source 
QTI HV (High Voltage) haptics is a module which can play haptics
effects for LRA or ERM with drive voltage up to 10 V. It has
several pattern sources built inside and each pattern source can
be used for playing different vibration effects.

Add the driver to support QTI HV haptics module, which will be
registered as an input FF device and can be controlled by calling
read/write/ ioctl APIs on the input device node.

help
This option enables device driver support for the high voltage haptics
peripheral found on Qualcomm Technologies, Inc. PMICs. The high voltage
haptics peripheral is capable of driving either LRA or ERM vibrators with
drive voltage up to 10 V, and its 5 integrated pattern sources can be used
for playing different vibration effects. To compile this driver as a module,
choose M here: the module will be called qcom-hv-haptics.
