There is no such tree. This rumor has recently gone around, but it is not true. You must trade a Deoxys from another game or through Pal Park to get one.
The only way to get a Deoxys in Pokemon Heart Gold is to either trade it from another Pokemon game that has it, or use an action replay code.
Deoxys is only available for capture in the 3rd gen games, so you have to transfer it over.
There is no such thing as a tree that leads to a man who gives you a Deoxys. You cannot get a Deoxys through normal game play in HeartGold. You must trade a Deoxys from another game.

You can change Deoxys into 1 of its Formes in Pokémon HeartGold and SoulSilver by interacting with 1 of the 4 Meteorites in Route 3 which is the route between Pewter City and Mt. Moon in the Kanto region.

Before I go on, I'd like to say that without a Cheating Device, you cannot get these Pokemon from HeartGold.Deoxys - Migrate from the GameBoy Pokemon Cartridges to Pokemon Pearl or Diamond by using the Pal Park. Afterwards, trade Deoxys to HeartGold or SoulSilver. (By the way, Deoxys can be found at Birth Island in the GameBoy Pokemon Cartridges.)Mew - It seems that Emerald is the only GameBoy Pokemon Cartridge that has Mew. Migrate Mew to Pokemon Pearl or Diamond, like Deoxys, and trade it to HeartGold or SoulSilver. (Mew can be found at Faraway Island in Emerald.)Celebi - Migrate from the GameBoy Pokemon Cartridges to Pokemon Pearl or Diamond by the Pal Park. Do the same with the others and trade Celebi to HeartGold or SoulSilver. (Nintendo Event is needed for this lovely Legendary.)
