mips: ralink: mt7621: define MT7621_SYSC_BASE with __iomem
commit a2cab953b4c077cc02878d424466d3a6eac32aaf upstream. So that MT7621_SYSC_BASE can be used later in multiple functions without needing to repeat this __iomem declaration each time Signed-off-by: John Thomson <git@johnthomson.fastmail.com.au> Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
