arm64: dts: rockchip: Enable wireless on rk3399-roc-pc-plus
The rk3399-roc-pc-plus board has an Ampak AP6256 Wi-Fi/Bluetooth
module.
Describe the Wi-Fi function on SDIO0 and the Bluetooth function on
UART0. Add the Bluetooth wake and shutdown pinctrl entries, enable
SDIO0 as a non-removable SDIO device, and add the power sequencing
delays needed by the module.
The module uses the RK808 CLKOUT2 output as its 32 kHz low-power
clock. Drop the duplicate HYM8563 clock-output-names property and
remove the same clock from the SDIO power sequencer so the Bluetooth
node can request the shared LPO clock directly.
