Subject: [PATCH] rsi: Fix module dev_oper_mode parameter description

The module parameters are missing dev_oper_mode 12, BT classic alone,
add it. Moreover, the parameters encode newlines, which ends up being
printed malformed e.g. by modinfo, so fix that too.

However, the module parameter string is duplicated in both USB and SDIO
modules and the dev_oper_mode mode enumeration in those module parameters
is a duplicate of macros used by the driver. Furthermore, the enumeration
is confusing.

So, deduplicate the module parameter string and use __stringify() to
encode the correct mode enumeration values into the module parameter
string. Finally, replace 'Wi-Fi' with 'Wi-Fi alone' and 'BT' with
'BT classic alone' to clarify what those modes really mean.

Fixes: 898b255339310 ("rsi: add module parameter operating mode")
