[ALSA] Remove sequencer instrument layer
Remove sequencer instrument layer from the tree. This mechanism hasn't been used much with the actual devices. The only reasonable user was OPL3 loader, and now it was rewritten to use hwdep instead. So, let's remove the rest of rotten codes. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@perex.cz>

51 *
52 * Provides conversion from a linear half-volume value in the range
53 * [0,8192] to a logarithmic attenuation value in the range 0 to 6.02dB.
54 * Halving the linear volume is equivalent to an additional 6dB of
55 * logarithmic attenuation. The algorithm used in log_from_linear()
56 * therefore uses this table as follows:
57 *
58 * - loop and for every time the volume is less than half the maximum
59 * volume (16384), add another 6dB and halve the maximum value used
60 * for this comparison.
61 * - when the volume is greater than half the maximum volume, take
62 * the difference of the volume to half volume (in the range [0,8192])
63 * and look up the log_table[] to find the nearest entry.
64 * - take the logarithic component of this entry and add it to the
65 * resulting attenuation.
66 *
67 * Thus this routine provides a linear->log conversion for a range of
68 * [0,16384] using only 386 table entries
69 *
70 * Note: although this table stores log attenuation in 8.8 format, values
71 * were only calculated for 6 bits fractional precision, since that is
72 * the most precision offered by the trident hardware.
