On Ventana boards the Gateworks System Controller is the only device on I2C1
(/dev/i2c-0) and it can NAK transfers if it is busy in an ADC loop. Because
this is a multi-function device with several slave addresses it is best to
add retries at the controller level instead of within each slave driver. This
adds a patch that adds 3 retries for i2c transactions only for Ventana boards
and only for I2C1

This is a backport of a2291badc355d58ead5c19ae0609468947416040 from thermal-soc
accepted upstream.
The IMX6Q/IMX6DL SoC's have a 2-bit temperature grade stored in OTP. Instead
of assuming 85C for passive cooling threshold and 100C for critical base
these thresholds off the thermal gade max CPU temperature:
- passive threshold: max - 10C
- critical threshold: max - 5C

Certain board revisions of the GW52xx support an SPI host controller with
a single chip-select going to an off board connector.
