During review of adding touchscreen-fw-name to the binding documentation it was brought up that there is a standard property name called "firmware-name" for this, which should be used. Since there are no users of touchscreen-fw-name yet, this commit adds documentation of "firmware-name" to the dt-binding documentation and switches the driver over to use this. This commit also makes the driver add a "silead/" prefix to the firmware name from dt before calling request_firmware. That the firmware files are stored under /lib/firmware/silead under Linux is an implementation detail and does not belong in devicetree.
