I couldn't come up with a simpler way to do this.
Selecting RSI_91X is not possible unless we make the BT
driver 'depend on WLAN_VENDOR_RSI && MAC80211',
which is even more backwards.

The problem here is that it's actually a reverse dependency:
the wlan driver calls into the bt driver.

What we could do is to make BT_HCIRSI a silent symbol
and have that selected by RSI_COEX, which can then
be user-visible. With that, the Kconfig structure would follow
what the code does.
