[PATCH v1 3/6] rockchip: rk3066: add Rockchip IDB block device as boot action

[Johan Jonker <jbx6244@gmail.com>]

From: Johan Jonker <jbx6244@gmail.com>

Add Rockchip IDB block device as boot action for rk3066.
When a key is pressed the NAND IDB blocks can be accessed
by a USB gadget like rockusb.
