arm64: dts: rockchip: rk3566/rk3568 boards: Fix pinctrl configuration for wireless-bluetooth

Browse Source 
The Linux OS uses the device tree to detect the wifibt module,
particularly the Bluetooth module's UART, identified via
`/sys/firmware/devicetree/base/pinctrl/wireless-bluetooth`.

Some RK3566/RK3568 board configurations redundantly register the pinctrl
for wireless-bluetooth, causing script failures in UART identification.

This commit removes the redundant node to resolve conflicts and ensure
correct UART identification for Bluetooth communication.
