This function returns -ENOENT when the property is missing (which the caller
might forgive) and also when the property is present but incorrectly
formatted (which many callers would like to report).
Update the error return value to allow these different situations to be

Since driver model is set up after arch_cpu_init(), that function cannot
use drivers. Add a new arch_cpu_init_dm() function which is called
immediately after driver model is ready, and can reference devices.
This can be used to probe essential devices for the CPU.

Support running U-Boot as a coreboot payload. Tested peripherals include:
- Video (HDMI and DisplayPort)
- SATA disk
- Gigabit Ethernet
- SPI flash
USB3 does not work. This may be a problem with the USB3 PCI driver or
something in the USB3 stack and has not been investigated So far this is
disabled. The SD card slot also does not work.
For video, coreboot will need to run the OPROM to set this up.
With this board, bare support (running without coreboot) is not available
as yet.

Since we support multiple dwc3 controllers to be existent at the same
time, in order to handle the interrupts of a particular dwc3 controller
usb_gadget_handle_interrutps should take controller index as an
argument.
Hence the API of usb_gadget_handle_interrupts is modified to take
controller index as an argument and made the corresponding changes to all
the usb_gadget_handle_interrupts calls.

There're 2 versions of motherboards that could be used in ARC SDP.
The only important difference for U-Boot is different NAND IC in use:
[1] v2 board (we used to support up until now) sports MT29F4G08ABADAWP
while
[2] v3 board sports MT29F4G16ABADAWP
They are almost the same except data bus width 8-bit in [1] and 16-bit
in [2]. And for proper support of 16-bit data bus we have to pass
NAND_BUSWIDTH_16 option to NAND driver core - which we do now knowing
board type we're running on.

The peach boards have their SDRAM start address at 0x20000000 instead of
0x40000000 which seems common for all other exynos5 based boards. This
means the layout set in exynos5-common.h causes the kernel be loaded
more then 128MB (at 0x42000000) away from memory start which breaks
booting kernels with CONFIG_AUTO_ZRELADDR

the same offsets from start of memory as the common exynos5 settings.
