From: Yan-Hsuan Chuang <yhchuang@xxxxxxxxxxx>
The module parameter is added to turn on/off lps support. And the
default value is "N". It is because that lps is not compatible with
bt-coexistence, WOW/PNO and the calibration routines for now.
After trade lps support off against these functionalities, it is
reasonable to set the parameter default to "N".
