dtoc: Collect priv/plat struct info from drivers

In order to output variables to hold the priv/plat information used by
each device, dtoc needs to know the struct for each. With this, it can
declare this at build time:

   u8 xxx_priv [sizeof(struct <name>)];

Collect the various struct names from the drivers.
