wil6210: enable AP/PCP power save
New FW has power save capability in AP/PCP mode. FW reports this to
driver with WMI_FW_CAPABILITY_AP_POWER_MANAGEMENT.
AP/PCP mode power save in FW is disabled by default. It can be enabled
by sending WMI_PS_DEV_PROFILE_CFG_CMD to FW as part of start_ap
sequence.
Several pre-conditions must be met for driver to enable this:
1. power save enabled from cfg80211
2. AP power save enabled from platform driver. This is reported from
platform driver with a new WIL_PLATFORM_CAPA_AP_PS
AP power save can be controlled via "ap_ps" debugfs.
