ti: omap: MAINTAINERS: move Benoît Cousson to CREDITS

Last email from Benoît Cousson was in 2014 [1], so remove him from
maintainers of the TI OMAP platform.  Stale maintainer entries hide
information whether subsystem needs help, has a bus-factor or is even
orphaned.

Benoît Cousson, thank you for TI OMAP contributions and maintenance.
