The 88AP510 chip (Marvell Dove) contains a LCD controller, a display
controller and two audio controllers.
Signed-off-by: Jean-Francois Moine <moinejf@free.fr>

v2 from Sebastian Hesselbarth remarks
- better names for the devices
- fix bad i2s interrupt controller
- 2 irq's by audio controller
- display controller added
