Hayato's Realtek WiFi/BT module has it's Bluetooth function wired to UART1.
Add and enable the relevant device nodes for it.
Signed-off-by: Chen-Yu Tsai <wenst@chromium.org> Reviewed-by: Nícolas F. R. A. Prado <nfraprado@collabora.com> --- Changes since v1: - Dropped unreferenced labels - Dropped GPIO line name comments - Fixed pinctrl node names - Dropped "output-enable" property - Added spacing between device nodes for consistency
