rockchip_dnl_key_pressed() looks for the ADC device by checking whether the device name starts with "saradc".
On RK3328, RK3576, RK3588 etc., the SARADC node is named "adc@...", so the device name no longer has the "saradc" prefix. As a result, U-Boot fails to find the SARADC device and does not sample the download key state. Do not rely on the DT node name. Match the bound Rockchip SARADC driver instead, which works for both "saradc@..." and "adc@..." node names.
