Add the TI drv260x haptics/vibrator driver. This device uses the input
force feedback to produce a wave form to driver an ERM or LRA actuator
device.
The initial driver supports the devices real time playback mode. But the
device has additional wave patterns in ROM. This functionality will be
added in future patchsets.

Many of Key device tree bindings uses the constant number as key code
which matches with kernel header key code and then comment as follows
for reference/better readability:
linux,code = <102>; /* KEY_HOME */
Create a DT header which defines all the key code so that DT key bindings
can use it as follows:
linux,code = <KEY_HOME>;
