Subject: [PATCH 2/3] ARM: orion: mark orion_ge00_mvmdio_bus_name as const

A section type mismatch warning shows up when building with LTO,
since orion_ge00_mvmdio_bus_name was put in __initconst but not marked
const itself:

include/linux/of.h: In function 'spear_setup_of_timer':
arch/arm/mach-spear/time.c:207:34: error: 'timer_of_match' causes a section type conflict with 'orion_ge00_mvmdio_bus_name'
 static const struct of_device_id timer_of_match[] __initconst = {
                                  ^
arch/arm/plat-orion/common.c:475:32: note: 'orion_ge00_mvmdio_bus_name' was declared here
 static __initconst const char *orion_ge00_mvmdio_bus_name = "orion-mii";
                                ^

This marks it const as well.
