lmb: Always compile arch_lmb_reserve() into U-Boot on arm

The arch_lmb_reserve() is called by lib/lmb.c lmb_reserve_common() even
if CMD_BOOT{I,M,Z} is not enabled. However, the arm32/arm64 variant of
arch_lmb_reserve() is only compiled in if CMD_BOOT{I,M,Z} is enabled.

This currently does not trigger build error, because there is an empty
weak implementation of arch_lmb_reserve(), however that is not the
function that should be used on arm32/arm64.

Fix this by moving the arch_lmb_reserve() implementation into common
code and always compile it in.
