bluetooth-device: fix rounding errors caused by few bt volume steps

one too low, so if bluetooth headset changes volume and that volume
is immediately set again for bluetooth device, bluetooth step drifts

sbc: added "cc" to the clobber list of mmx inline assembly

In the case of scale factors calculation optimizations, the inline
assembly code has instructions which update flags register, but
"cc" was not mentioned in the clobber list. When optimizing code,
gcc theoretically is allowed to do a comparison before the inline
assembly block, and a conditional branch after it which would lead
to a problem if the flags register gets clobbered. While this is
apparently not happening in practice with the current versions of
gcc, the clobber list needs to be corrected.

Regarding the other inline assembly blocks. While most likely it
is actually unnecessary based on quick review, "cc" is also added
there to the clobber list because it should have no impact on
performance in practice. It's kind of cargo cult, but relieves

sbc: new 'sbc_calc_scalefactors_j' function added to sbc primitives

The code for scale factors calculation with joint stereo support has
been moved to a separate function. It can get platform-specific
SIMD optimizations later for best possible performance.

But even this change in C code improves performance because of the
use of __builtin_clz() instead of loops similar to what was done
to sbc_calc_scalefactors earlier. Also technically it does loop
unrolling by processing two channels at once, which might be either
good or bad for performance (if the registers pressure is increased
and more data is spilled to memory). But the benchmark from 32-bit
x86 system (pentium-m) shows that it got clearly faster:
