arm64: dts: rockchip: Fix the BT clock-names on rk3399-leez-p710

This commit changes the bluetooth clock-names property from ext_clock
to txco to resolve a dt-schema warning.

[Severity: Low]
Should this be named lpo instead of txco?

The clock provided by <&rk808 1> corresponds to the RK808 PMIC's clkout2,
which is a fixed 32.768 kHz clock.

According to the brcm,bluetooth.yaml dt-bindings, an external low-power
32.768 kHz clock must be named lpo, whereas txco is reserved for
high-frequency reference clocks. Other boards with the exact same hardware
configuration correctly use lpo for <&rk808 1>.
