[PATCH 13/14] lmb: Mark arch_lmb_reserve() as weak symbol

[Marek Vasut]

Mark arch_lmb_reserve() weak on architecture level, so it can be
overridden if necessary. This might be necessary if there is some
sort of architectural exception where e.g. more LMB areas have to
be reserved.

Note that sandbox now needs an empty implementation of
arch_lmb_reserve().
