[PATCH v2] Bluetooth: hci_qca: disable power control for WCN7850 when bt_en is not defined

[Shuai Zhang]

On platforms using an M.2 slot with both UART and USB support, bt_en is
pulled high by hardware. In this case, software-based power control
should be disabled. The current platforms are Lemans-EVK and Monaco-EVK.

Add QCA_WCN7850 to the existing condition so that power_ctrl_enabled is
cleared when bt_en is not software-controlled (or absent), aligning its
behavior with WCN6750 and WCN6855

Sorry, I forgot to include the version update differences. v2 only 
updates the commit content
and adds explanations regarding hardware management.
