Input: synaptics-rmi4 - allow to add attention data
The HID implementation of RMI4 provides the data during the interrupt (in the input report). We need to provide a way for this transport driver to provide the attention data while calling an IRQ. We use a fifo in rmi_core to not lose any incoming event.
