[PATCH v2 0/6] Centralise common functions in IPA modules

[Daniel Scally]

Hello all

This series attempts to centralise some common things that are cropping up in
multiple different IPAs. A helpers file is added for functions to be defined in
that can be used in each IPA module so that a single common implementation is
used across the board. Additionally the common hardcoding of default sensor
delay values in pipeline handlers is switched to using values from the sensor's
CameraSensorProperties class - the values there are those from the Rpi handler
if available, or the defaults otherwise.

Thanks
Dan
