arm64: dts: imx8mp-verdin: use uart4 as bt uart
The PCB of the hardware version V1.1 uses the UART4 (ECSPI2 pins) for
the Bluetooth UART, therefore move it to the Wi-Fi module device tree.
Move regular UART4 usage to non-WiFi only.
While at it also split Bluetooth specific pin from pinctrl_wifi_ctrl
into separate pinctrl_bluetooth_ctrl as that might be needed to run the
proprietary driver stack.
