[PATCH v2 2/2] arm64: dts: rockchip: Fix the BT clock-names on rk3399-leez-p710

[Fabio Estevam]

According to brcm,bluetooth.yaml, the correct clock-names to describe
the 32768kHz Low Power Oscillator is "lpo".

Change it accordingly to fix the following dt-schema warning:

clock-names: 'oneOf' conditional failed, one must be fixed:
        ['ext_clock'] is too short
        'extclk' was expected
        'txco' was expected
        'lpo' was expected

Changes since v1:
- Use "lpo" name instead. (Sashiko)
