Bernhard Beschow 54e54e594b hw/i2c/imx: Always set interrupt status bit if interrupt condition occurs 
According to the i.MX 8M Plus reference manual, the status flag
I2C_I2SR[IIF] continues to be set when an interrupt condition
occurs even when I2C interrupts are disabled (I2C_I2CR[IIEN] is
clear). However, the device model only sets the flag when I2C
interrupts are enabled which causes U-Boot to loop forever. Fix
the device model by always setting the flag and let I2C_I2CR[IIEN]
guard I2C interrupts only.

Also remove the comment in the code since it merely stated the
obvious and would be outdated now.
