[PATCH] drivers/of: Fix sparc build failure caused by of_alias_scan

[Grant Likely <grant.likely@secretlab.ca>]

Commit 750f463a, "dt: add of_alias_scan and of_alias_get_id" breaks
platforms that don't use CONFIG_OF_FLATTREE, like SPARC and OLPC.  Fix
it by only building it on platforms using the flat tree.

Hi Linus,

Hand me the paper bag, I completely screwed up that last commit.  The
previous commit fixes imx, but breaks SPARC.  I apologize, and rightly
accept any due punishment.

This patch fixes it, and it is also pushed out to devicetree/next:
