xen: Introduce __initconst to store initial const data

It's possible to have 2 type (const and non-const) of data in the same
compilation unit. Using only __initdata will result to a compilation error:

    error: $variablename causes as section tupe conflict with $variablename2

because a section containing const variables is marked read only and so cannot
contain non-const variables.
