Add HBoost register base address so that supported voltage range for
haptics peripheral can be read.

Add properties to specify nvmem for haptics which can be used for storing
closed-loop brake calibration settings.

Add optional property "qcom,fifo-empty-threshold" to specify the
FIFO empty threshold. The module would generate fifo-empty
interrupt when the number of samples in the FIFO is less than this
threshold.

Hardware with revision 2 is changed to use 8-bit FIFO memory while
revision 1 is using 9-bit FIFO memory. To unify the data assignment
from devicetree, change to use 8-bit data for "qcom,wf-fifo-data"
property. Software can expand the 8-bit data to 9-bit for V1
hardware accordingly.

Add a subnode to define a regulator device to control the online status
of the SWR slave in haptics module.

Qualcomm Technologies, Inc. (QTI) High Voltage (HV) PMIC haptics
modules can support up to 10 V voltage to drive either ERM or LRA.
It has an integrated module to support auto resonance detection
and correction for LRA actuator. It can play different vibration
effects with different pattern sources. It also has an integrated
brake module which can work in different modes to use BEMF for
quick vibration stop.

Add device tree bindings for Qualcomm Technologies, Inc. QPNP
Power-on devices. These are PMIC peripherals which manage PMIC
power on, power off, key presses, and other related activities.
