Init data marked const should be annotated with __initconst for
correctness and not __initdata.  In some cases the array gathering
references to that data has to be marked const as well. This fixes
LTO builds that otherwise fail with section mismatch errors.

Signed-off-by: Nicolas Pitre <nico@linaro.org>

Changes since v1: Many more "const" added throughout. More coverage in 
my LTO build.

Still gives me error on mxs_defconfig:

                        ^
A "const" is still missing here.
Argh...
