Subject: [PATCH] Tools: Topology2: Change in capture gain curve_duration to 50
 ms

This change increases the ramp duration from 20 ms to 50 ms. It
lowers the peak load of peak volume component due to longer same
gain value blocks. The internal update rate for gain becomes 250 us
instead of 125 us. The longer fade-in ramp also conceals better
possible analog capture start transients.

This changes for 4ch capture for gain.11.1 in sof-hda-generic-4ch.tplg
from

CPU_PEAK(MAX) = 21.95
PEAK(MAX)/AVG(AVG) = 7.51

to

CPU_PEAK(MAX) = 9.07
PEAK(MAX)/AVG(AVG) = 3.12
