This patch adds a small delay, so when the 3.3V regulator comes on it delays a bit before the subsequent regulators can come on. This reduces the inrush current a bit on the external DC power supply to help prevent a situation where the sourcing power supply cannot source enough current and overloads and the kit fails to start.
