amazon: MAINTAINERS: change to odd fixes and Tsahee Zidenberg to CREDITS

Last email from Tsahee Zidenberg was in 2016 [1], so move Tsahee from
Amazon platform maintainers to credits (thank you for your contributions
and maintenance!).  Stale maintainer entries hide information whether
subsystem needs help, has a bus-factor or is even orphaned.

The Amazon platform still has active maintainer - Antoine Tenart -
however there was no maintenance activities coming from Antoine.  All
my patches from last 4 years related to Amazon remained unanswered - no
acks, no picks - so document the actual not active status of the
platform by changing it to Odd Fixes.
