[PATCH v11 1/7] wifi: rtw88: add the RTL8723B chip type and SDIO helper

From: Luka Gejak <redacted>

The RTL8723B is a 802.11n combo chip whose SDIO variant, RTL8723BS, runs
a Realtek vendor firmware that differs from the firmware used by the
other rtw88 8723 family devices. Supporting it needs a number of small
adjustments spread across the shared core, all of which have to be
restricted to this one chip and bus combination.

Add the chip type and a helper that tests for it, so the changes that
follow can be gated without repeating the chip and bus comparison.
