rtw88: remove misleading module parameter rtw_fw_support_lps
The module parameter rtw_fw_support_lps is misleading. It
is not used to represent the firmware's property, but to
determine if driver wants to ask firmware to enter LPS.
However, driver should better enable/disable PS through
cfg80211_ops::set_power_mgmt instead.
For example, one could use iw command to set PS state.
$ sudo iw wlanX set power_save [on/off]
So rtw_fw_support_lps should be removed because it is
misleading and useless. Instead of checking the parameter,
set PS mode according to IEEE80211_CONF_PS.
