ath9k: Cleanup MCI init/deinit routines
...
This patch simplifies the buffer allocation functions
for MCI and removes unneeded memset calls. Also, a couple
of unused variables are removed and a memory leak in DMA
allocation is fixed.

ath9k_hw: make bluetooth coexistence support optional at compile time
...
Many systems (e.g. embedded systems) do not have wifi modules connected to
bluetooth modules, so bluetooth coexistence is irrelevant there. With the
addition of MCI support, ath9k picked up quite a bit of extra code that
can be compiled out this way.
This patch redefines ATH9K_HW_CAP_MCI and adds an inline wrapper for
querying the bluetooth coexistence scheme, allowing the compiler to
eliminate code that uses it, with only very little use of #ifdef.
On MIPS this reduces the total size for the modules by about 20k.
