rtlwifi: rtl8723be: Fix loss of signal
commit 78dc897b7ee67205423dbbc6b56be49fb18d15b5 upstream.
In commit c713fb071edc ("rtlwifi: rtl8821ae: Fix connection lost problem
correctly") a problem in rtl8821ae that caused loss of signal was fixed.
That same problem has now been reported for rtl8723be. Accordingly,
the ASPM L1 latency has been increased from 0 to 7 to fix the instability.
