SYSLINK: ipc - fixes in proc4430 and platform.

This patch fixes the issues found in..
	<1> platform.c:
		- calling platform_mem_unmap() on all addreses
                	on which we have called platform_mem_map().
		- calling proc_mgr_detach for SysM3 and AppM3.
	<2> -proc4430.c:
		- proc4430_detach() fixed to unmap all reqd.
			addresses.
		- cleanup
