input: add snapshot of qpnp-power-on driver 



The qpnp-power-on driver provides support for key presses via
several key specific PMIC inputs.  It also supports reading
power-on reasons and configuring the power-off type (i.e.
restart, shutdown, etc).

This snapshot is taken as of msm-4.19
commit 47598dd0e809 ("input: misc: qpnp-power-on: add support
to power off a modem chip").

Note that support for boot_reason, cold_boot, and ship_mode
configuration was removed as these have unmet dependencies and
are no longer needed.
