This patch set adds a driver for RTL8723CS, which is used in the
Pinephone and a few other devices. It is a combined wifi/bluetooth
device, the wifi part is called RTL8703B. There is already a mainline
driver for the bluetooth part. RTL8703B is similar to the RTL8723D
chip already supported by rtw88. I've been using the out-of-tree
rtl8723cs driver as reference.

Station and monitor mode work well enough for daily use on my
Pinephone, I have not tested other modes yet. WOW firmware is
declared, but WOW isn't implemented yet. RX rates stay fairly low
still.

Ping-Ke Shih kindly offered to add the required s-o-b for the firmware
and help get it into linux-firmware when it's time, for testing now
please see the code I used to extract firmware from the out-of-tree
driver [1].

Thanks to Ping-Ke Shih for advice, and Ondřej Jirman for debug logs!

v2:
  * Parse PHY status using struct instead of macros
  * Prefer MAC from EFUSE if available, move retrieving MAC from DT to
    a separate function
  * Tidy up wait for IQK to be done, replace mdelay loop with
    read_poll_timeout
  * Set dual author for rtw88_8723x
  * Add missing "static" to rtw8723x function declarations, fixes
    build failure when not built as a module
  * Various style fixes

v3 has only minor changes requested in review, so I hope it's good to
merge now:
  * rtw8703b.h: #include rtw8723x.h instead of linux/types.h and
    linux/compiler_attributes.h
  * rtw8703b_tables.c: #include rtw8703b_tables.h
  * rtw8703b.c: define TRANS_SEQ_END without braces (checkpatch.pl
    doesn't like this, but I assume maintainer request overrides it)
