[PATCH] regulator: core: add debug print for regulator_resolve_supply

[Ahmad Fatoum]

Starting with commit 324bd9bbe7e8 ("regulator: recursively enable/disable
regulator dependency tree"), regulator operations may affect more than
just the one regulator being enabled. Place a debug print, so it's
easier to follow the dependency chain.
