HID: i2c-hid: disable interrupt on suspend
When an I2C HID device is powered of during system sleep, as a result of removing its power resources (by the ACPI core) the interrupt line might go low as well. This results inadvertent interrupt and wakes the system from sleep immediately. To prevent this we disable the device interrupt in the drivers suspend method and enable it on resume. The device can still wake the system up if it is wake capable (this also means that not all of its power will be removed to keep the interrupt line high).
