memory: ti-aemif: Revert "memory: ti-aemif: don't needlessly iterate over child nodes"

This reverts commit 23a641d5c2bce4c723fff9118a5d865ee6b9d05a.

The first-level children of the aemif node are not the device nodes (ones
containing the 'compatible' property) but the chip-select nodes which
instead have their own children.

of_platform_populate() will skip such nodes so we must indeed iterate
over the direct children of the aemif node. The problem here is that we
never call of_platform_depopulate() as it takes the root device as
argument. We only have an unpopulated chip-select nodes so we will leak
these devices if any of the calls to of_platform_populate() fails.

I don't have a batter idea right now but my patch was not correct so we
need to revert it. While at it: at least use the scoped variant of the
OF node iterator. Down the line, we should find a better solution to fix
this potential resource leak in error path.
