adxl345: Support recording data from multiple ADXL345's in one run, and more. (#5224) 

Add PROBE and CHIP to TEST_RESONANCES

Since it's possible to specify more than one chip
in TEST_RESONANCES the CHIP parameter has been
renamed to CHIPS

#### TEST_RESONANCES
`TEST_RESONANCES AXIS=<axis> OUTPUT=<resonances,raw_data>
[NAME=<name>] [FREQ_START=<min_freq>] [FREQ_END=<max_freq>]
[HZ_PER_SEC=<hz_per_sec>] [INPUT_SHAPING=[<0:1>]]`: Runs the resonance
[HZ_PER_SEC=<hz_per_sec>] [CHIPS=<adxl345_chip_name>]
[POINT=x,y,z] [INPUT_SHAPING=[<0:1>]]`: Runs the resonance
test in all configured probe points for the requested "axis" and
measures the acceleration using the accelerometer chips configured for
the respective axis. "axis" can either be X or Y, or specify an
arbitrary direction as `AXIS=dx,dy`, where dx and dy are floating
point numbers defining a direction vector (e.g. `AXIS=X`, `AXIS=Y`, or
`AXIS=1,-1` to define a diagonal direction). Note that `AXIS=dx,dy`
and `AXIS=-dx,-dy` is equivalent. If `INPUT_SHAPING=0` or not set
(default), disables input shaping for the resonance testing, because
and `AXIS=-dx,-dy` is equivalent. `adxl345_chip_name` can be one or
more configured adxl345 chip,delimited with comma, for example
`CHIPS="adxl345, adxl345 rpi"`. Note that `adxl345` can be omitted from
named adxl345 chips. If POINT is specified it will override the point(s)
configured in `[resonance_tester]`. If `INPUT_SHAPING=0` or not set(default),
disables input shaping for the resonance testing, because
it is not valid to run the resonance testing with the input shaper
enabled. `OUTPUT` parameter is a comma-separated list of which outputs
will be written. If `raw_data` is requested, then the raw
accelerometer data is written into a file or a series of files
`/tmp/raw_data_<axis>_[<point>_]<name>.csv` with (`<point>_` part of
the name generated only if more than 1 probe point is configured). If
`resonances` is specified, the frequency response is calculated
(across all probe points) and written into
`/tmp/raw_data_<axis>_[<chip_name>_][<point>_]<name>.csv` with
(`<point>_` part of the name generated only if more than 1 probe point
is configured or POINT is specified). If `resonances` is specified, the
frequency response is calculated (across all probe points) and written into
`/tmp/resonances_<axis>_<name>.csv` file. If unset, OUTPUT defaults to
`resonances`, and NAME defaults to the current time in
"YYYYMMDD_HHMMSS" format.
