[PATCH 14/14] lmb: Switch imx board_lmb_reserve() to arch_lmb_reserve()

[Marek Vasut]

This function is clearly architecture specific code, not board specific
code. The only difference from the generic arm arch_lmb_reserve() is the
extra reservation of 16k of memory below the stack bottom, rather than
the default 4k. Switch this from board_lmb_reserve() to arch_lmb_reserve()
and use arch_lmb_reserve_generic() with 16k stack reservation parameter
instead of replicating older version of arch_lmb_reserve() here.
