HID: i2c_hid: enable i2c-hid devices to suspend/resume asynchronously
i2c-hid devices' suspend/resume are usually time-consuming process. For example, the touch controller(i2c-ATML1000:00) on ASUS T100 tablet takes about 160ms for suspending and 120ms for resuming. This patch enables i2c-hid devices to suspend/resume asynchronously. This will take advantage of multicore and speed up system suspend/resume process.
