[U-Boot] [PATCH] Kirkwood: declare mpp config static and const

Change the prototype of kirkwood_mpp_conf() from
void kirkwood_mpp_conf(u32 *mpp_list)
to
void kirkwood_mpp_conf(const u32 *mpp_list)
Now we can declare the kwmpp_config static and const where possible.

This was spotted by Mike in an earlier patch series (Kirkwood: add lschlv2
and lsxhl board support). Declaring the mpp_config static avoids generating
the array on the stack.
This was compile tested on all kirkwood boards and tested on the lschlv2.
