Add WMI command support to force power save on all the
active MLO links for a defined number of beacon periods.
Force power save allows the firmware to suspend STA links
for X beacon periods and remain asleep even if the AP
advertises TIM as opposed to regular power save mode where
STA links wake up if the AP indicates that it has buffered
data to send.
