ARM: integrator/versatile: fix NOMMU warnings
On NOMMU kernels, the io_desc variables are unused because we don't use the MMU to remap the MMIO areas. Marking these variables as __maybe_unused easily avoids the otherwise harmless warnings like warning: 'versatile_io_desc' defined but not used Signed-off-by: Arnd Bergmann <arnd@arndb.de> Cc: Linus Walleij <linus.walleij@linaro.org> Cc: Russell King <linux@arm.linux.org.uk>
