Do low level power init in system_init(). This can be needed
since imx233 must be able to frequecy scale atfer system_init()
and kernel_init() and this is only possible if power system was
initialised.

Make sure DCDC is running at boot (it is disabled by default when
5V is present and we don't want to rely on the bootloader to
change this).
When changing the voltage on a regulator, it usually takes 2ms for
the voltage to stabilize. In DCDC mode, there is an irq to notify
about the event so use it ! This is especially important when
changing cpu frequency because increasing the cpu freq while the
voltage is rising is unreliable.

Remove the old debug stuff about VDDx and add a clean api to
get/set the regulator (VDDD, VDDA, VDDIO, VDDMEM). This is useful
for proper frequency scaling.

- now identity map dram uncached and have a cached and buffered virtual alias
- rework dma to handle virtual to physical pointers conversion
- fix lcd frame pointer
- implement usb detection properly
- implement bootloader usb properly
- allow the bootloader to disable MMC windowing (useful for recovery)
