The LPT/WPT IOSF sideband is unrelated to pcode or VLV/CHV IOSF
sideband. It's just confusing to piggyback on the same mutex. Add a
dedicated lock with init and cleanup functions.

Now that intel_sideband.[ch] has been decluttered, it's pure lpt/wpt
iosf sideband. Let's call it intel_sbi, following the function naming.
