mwifiex: module parameter for deep sleep configuration

This patch adds module parameter for auto deepsleep configuration.
By default, module_param is 0 and auto deep sleep is enabled.
If mwifiex driver is loaded with disable_auto_ds=1, deep sleep
configuration would not be downloaded to FW and FW would not enter
deepsleep upon initializing.
