Attached patch should fix this problem. Compile-tested only. 

I've already applied this to the code that I am pushing upstream. So
this should be dropped eventually.

Patch

Subject: [PATCH 195/195] TWL4030: RX51: Mark board data as __initdata

Mark rx51 board data as __initdata so that compiling with
CONFIG_DEBUG_SECTION_MISMATCH=y will not throw warnings.
