IioDeviceList is a simple application which demonstrates how to use the
shared libiio component to enumerate the IIO devices avaialble in the
system.

This app applies to a sensor which is not included on any mangOH.

An at24 eeprom device is created from the mangOH red kernel module. The
eeprom contents can be read from /sys/bus/i2c/devices/0-0051/eeprom.

rtc-pcf85063 is an I2C RTC chip that exists on the mangOH Yellow. This
driver was copied from the mainline Linux kernel. rtc_sync is a kernel
module that sets the system time from rtc1 when the module is loaded and
then periodically syncs the system time to the RTC if the system time is
changed.

Prior to Legato 18.07.0, there was bug (LE-10550) in Legato which caused
the supervisor to get stuck in an infinite loop if two different mdefs
included in a system depended on the same mdef.  As a workaround the
dependency of bmp280.mdef on iio-kfifo-buf.mdef was commented out.  Now
that this bug is resolved, the dependency can be restored.

Remove spisvc from the mangOH SDEF since the default.sdef from Legato
18.07.0 includes spisvc and mangOH.sdef includes default.sdef indirectly
via wifi.sdef.

The bq27xxx module now compiles for both 9x15 and 9x07 based targets.
The module has not been tested yet.

Specifically, MANGOH_WP_CHIPSET_9X15 and MANGOH_WP_CHIPSET_9X07
variables have been defined.  This allows for decision making in .cdef
and .adef files based upon which module is being targeted.  This is
useful when requiring libraries and the versions of the libraries differ
between chipsets.

Rather than requiring a yocto re-build to support the CAN IoT card, the
relevant kernel module code has been taken out of tree.  For 9x15 based
modules (wp75, wp85) use the modules in the can_9x15 directory.  For
9x07 based modules (wp76, wp77), use the modules in the can_9x07
directory.  The can_common/can_iot module instantiates an mcp251x device
with the appropriate platform data for using the CAN IoT card in a
mangOH Red.

* Rename .mdef files to remove numeric prefix that was used to force
  kernel modules to load in the required order
* Use new "requires module" feature of .mdef files to specify
  dependencies.
* Update mtwifi script based on module renaming

BMI088 has typo for accel calculation which is incorrect.  Updated
calculation to be correct.

Updated sysfs config show and restore functions to use library calls
