the battery node and this is incorrect.
This patch exposes both of them on the charger node rather

Make trigger delay configurable through device tree with
trigger-delay-ms property.
Trigger delay is the time to wait before starting shutdown
sequence after trigger line assertion.
Trigger delay must take into account the OFFT time configured
with the capacitor connected to OFFT pin of the LTC2952 chip.
Basically, the higher the capacitance connected to OFFT pin,
the larger trigger delay must be.

Adds 80000 us sleep when the usb cable is plugged in to hopefully avoid
bouncing contacts.
Upon pluging in the usb cable vbus will bounce for some time, causing cpcap to
dissconnect charging due to detecting an undervoltage condition. This is a
scope of vbus on xt894 while quickly inserting the usb cable with firm force,
probed at the far side of the usb socket and vbus loaded with approx 1k:
http://uvos.xyz/maserati/usbplug.jpg.
As can clearly be seen, vbus is all over the place for the first 15 ms or so
with a small blip at ~40 ms this causes the cpcap to trip up and disable
charging again.
The delay helps cpcap_usb_detect avoid the worst of this. It is, however, still
not ideal as strong vibrations can cause the issue to reapear any time during
charging. I have however not been able to cause the device to stop charging due
to this in practice as it is hard to vibrate the device such that the vbus pins
start bouncing again but cpcap_usb_detect is not called again due to a detected
disconnect/reconnect event.

Avoid logging probe defer information for default loglevel
configurations. This is only required for debugging probe
defer issues, which requires enabling debug messages for
other subsystems.
This dev_info() message predates having deferred devices
information available in /sys/kernel/debug/devices_deferred,
which is generally more useful.

makes the code slightly more readable and removes some
lines of code. It also removes PROBE_DEFER errors being
logged by default, which are common when the battery is
waiting for the charger driver to be registered.
This also cleans up a useless goto and instead returns
