drm/xe/i2c: Fix the interrupt handling
The platforms that support the interrupt from the I2C
adapter can not handle the amount of interrupts the adapter
generates because of the way the IRQ is routed in the
hardware. The I2C controller driver has to be kept in
polling mode because of that.
The AMC MCU can still generate critical alerts that have to
be handled. The interrupt from SMBus Alert is left enabled
and handled separately in the Xe. The alerts from the AMC
will cause the device to be declared wedged for now.
