WORKAROUND: arm64: dts: qcom: monaco-evk: Remove WCN6855 PMU node to bypass pwrseq flow

There is a conflict between the current DTS configuration and the driver
behavior for the WCN6855 Bluetooth path. With the PMU node in place, the
driver takes the pwrseq code path unintentionally, which leads to Bluetooth
failing to power up during an on -> off -> on transition.

To unblock function, temporarily remove the WCN6855 PMU node so that the
driver follows the non-pwrseq path and avoids the unexpected sequence.

This is a TEMPORARY WORKAROUND. Once a proper M.2 binding/solution is
upstreamed, will re-submit both DTS and driver changes aligned with the
M.2 model.
