Subject: [PATCH 2/4] brcm80211: deinline dma64_dd_upd, save 157 bytes

Automated script discovered that without forced inlining,
gcc-4.7 generates smaller code for this function.

There is no need to declare static functions inline anyway:
nowadays gcc detects single-callsite static functions
which benefit from inlining.

In this case, function is large and has two callsites.
