[patch] fix typo in sim_state documentation

[Mike Frysinger <vapier@gentoo.org>]

the sim-base.h suggests you declare cpu storage in sim_state, but the proposed 
code causes build failures in some files such as sim-core and sim-cpu.c (since 
STATE_CPU() is supposed to return an lvalue).

it also doesnt make sense with the common sim_cpu_alloc_all() which 
dynamically allocates the memory for each cpu.

	* sim-base.h: Declare sim_state.cpu as a pointer in the comment.  Drop
	& from the STATE_CPU() examples.
