board: ryu: Match Samus double tap behavior.
Increase the change of false positive, but make double feels like Samus:
- increase time beetwen tap to 500ms
- decrease tap threshold to 100mg (actually 62.5mg)
- increase ODR during TAP.
BRANCH=smaug
BUG=b:24440423
TEST=check Ryu and Samus side by side, their tap behavior is more
similar.
