MFD: ucb1x00-core: scan drivers in same order they're registered
Cosmetic patch to scan the list of drivers in the order that the drivers are registered, rather than the reverse order. This avoids surprises when drivers get probed in the reverse order, and input devices get registered in a different order due to bind/unbind than from boot.
