The function idle_loop() is referenced only in domain.c.
Change its linkage from external to internal by adding the storage-class
specifier static to its definitions.
Since idle_loop() is referenced only in inline assembly, add the 'used'
attribute to suppress unused-function compiler warning.
Also, this patch resolves indirectly a MISRA C 2012 Rule 8.4 violation warning.
