Subject: [PATCH V5 1/2] ath11k: add WMI calls to manually add/del/pause/resume TWT dialogs

From: John Crispin <[email protected]>

These calls are used for debugging and will be required for WFA
certification tests.

Changes in V5
* Setting and resetting of twt_enabled in WMI functions
* ath11k_dbg() instead of ath11k_info() in ath11k_wmi_twt_add_dialog_event()
* Made WMI error messages more readable
