[PATCH 0/2][SRU][B/E/F/OEM-OSP1-B] Fix Wi-Fi association after being off-ed and on

[You-Sheng Yang]

BugLink: https://bugs.launchpad.net/bugs/1878296

[Impact]
With the rtl8723bu wireless adapter, if the wifi is turned off and then
turned on again, the system can't connect to a wireless network until
the system is rebooted.

[Fix]
Commit e542e66b7c2e("rtl8xxxu: add bluetooth co-existence support for
single antenna"), which landed v5.5 and as its subject suggests, support
bluetooth co-existence for RTL8723BU and fixes WiFi disconnection
problem when Bluetooth is in action.

Commit a9bb0b515778("rtl8xxxu: Improve TX performance of RTL8723BU on
rtl8xxxu driver") was added as a prerequisite to aforementioned fix.

[Test Case]
1. Turn on Wi-Fi and get associated with some AP.
2. Pair some bluetooth device.
3. Turn off Wi-Fi and turn again.
4. Expect Wi-Fi reconnects to the previous associated AP

[Regression Potential]
Low. Both commits only affect RTL8723BU.
