Remove stale references to Cell BE

  While reading some code i noticed we're still referencing Cell BE in a couple
parts. This patch removes those.

gdb/ChangeLog:

2019-12-30  Luis Machado  <luis.machado@linaro.org>

	* proc-service.c (get_ps_regcache): Remove reference to obsolete
	Cell BE architecture.
	* target.h (struct target_ops) <thread_architecture>: Likewise.

Thanks, this is ok, but see one comment below.

Should this say "This architecture is used"?

Probably. That didn't read right, but i opted not to change it. I'll 
patch this and push the patch then.

Thanks!
