dt-bindings: clock: qcom,gcc-sm8250: add missing bi_tcxo_ao clock

The initial SM8250 GCC driver added in commit 3e5770921a88 ("clk: qcom:
gcc: Add global clock controller driver for SM8250") already consumed it
on the clock.  This fixes warnings like:

  sm8250-xiaomi-elish-csot.dtb: clock-controller@100000: clock-names: ['bi_tcxo', 'bi_tcxo_ao', 'sleep_clk'] is too long
