i2c: designware: Disable SMBus interrupts to prevent storms from mis-configured firmware
When probing the I2C master, disable SMBus interrupts to prevent
storms caused by broken firmware mis-configuring IC_SMBUS=1; the
handler never services them and a mis-configured SMBUS Master
extend-clock timeout or SMBUS Slave extend-clock timeout can
flood the CPU.
