ee5931d488 imx: ventana: add 'gsc wd' command for enabling and disabling GSC watchdog
This adds information about the Gateworks System Controller to the gsc command
such as the firmware version, firmware CRC and status of the GSC watchdog
(if its enabled and if its tripped).

Additionally the 'gsc wd' command can be used to enable or disable the
watchdog with the following usage:
 gsc wd enable [30|60]
 gsc wd disable

Note that the GSC registers are battery-backed by the GSC coincell so once
eanbled, they remain enabled across power-cycles or until either the GSC
firmware has been updated or FLASH has been re-programmed by the Gateworks
JTAG adapter.

16e369f5ec imx: ventana: remove GSC hwmon voltage rail min/max test
The min/max of each depends not only on board but on CPU. Simplify by removing
this rarely needed and difficult to maintain feature and just display the
rails and their values.

e5131d53bf imx: ventana: add appropriate delay following GSC i2c write
The Gateworks System Controller EEPROM config is flash based. Add a delay
following writes to avoid errors on back-to-back writes.

59189a8b26 ventana: Add Gateworks Ventana family support
Gateworks Ventana is a product family based on the i.MX6.  This
patch adds support for all boards in the Ventana family. Where
possible, data from the boards EEPROM is used to determine various
details about the board at runtime.
