This is a re-implementation of work done in 497117a7 which was
overwritten by merge commit 03608c12.

Reduce repetition by passing offsets rather than absolute GPIO numbers
to the gpio_initial_status and gpio_final_status functions.

Use devm_gpio_request_one instead of devm_gpio_request + gpio_direction_output

These apps may be added back into the SDEF once they are published.

Updated BQ25601 and got source from https://github.com/mangOH/mangOH/tree/master/linux_kernel_modules/bq24296

When the hardware revision is not passed explicitly as a module parameter, the probe now reads the
board EEPROM to discover the hardware revision.

mangOH Red prior to DV5 were pre-production boards. These configurations
haven't been tested or maintained in a long time, so it's better to
remove support for them so that users don't get the false impression
that they are supported.

The yellow_* targets all build successfully using the latest toolchains
so enable building for yellow under the "all" target.

Move the CAN IoT card fragment into a .sinc file to de-clutter the main
SDEF file.

Replace references to MANGOH_CAN_9X15 with MANGOH_WP_CHIPSET_9X15 and
eliminate the MANGOH_CAN_9X15 variable. There is no neet to have a
CAN-specific variable for chipset identification.

As of WP85/WP75 Release 16, all WP modules support the MT7697 based WiFi
on the mangOH Red board and thus it is no longer necessary to
distinguish between the modules when deciding what is included in the
mangOH.sdef.

WP85/75 release 16 properly supports the battery service, so the #if
statement in the SDEF can be removed and the battery service can be
included for the mangOH Red regardless of which module is being used.

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.
