[ Upstream commit 9f67f7583e77fe5dc57aab3a6159c2642544eaad ]

Probe deferrals aren't actual errors, so silence the error message in
case the PWM cannot yet be acquired.

[ Upstream commit 791ebc9d34e9d212fc03742c31654b017d385926 ]

The three INA3221_CONFIG_MODE macros are not correctly defined here.
The MODE3-1 bits are located at BIT 2-0 according to the datasheet.

So this patch just fixes them by shifting all of them with a correct
offset. However, this isn't a crital bug fix as the driver does not
use any of them at this point.
