pxe: Fix pxe boot with FIT image

When FIT image is used, a single image provides kernel, device
tree and optionally ramdisk. Argc and argv need to be adjusted
to support this.

Test cases:
1. Booting with legacy images
2. Booting with legacy images without initrd
3. Booting with FIT image
Test commands:
1. pxe get && pxe boot
2. sysboot

On the raspberry pi, you can disable the serial port to gain dynamic frequency

mapped to GPIO15 and disables the mini uart if it is not mapped properly.

The reason for the breakage is that the warp board is using the DDR
configuration from mx6slevk. A fundamental difference between warp and
mx6slevk is that warp only uses one DDR chip select while mx6slevk uses two.

The imx_ddr() function calculates the RAM size in runtime by reading the
values of registers MDCTL and MDMISC.

So in order to fix this warp boot issue, create a imximage DDR file specific
to warp, where the MDCTL register is configured to only activates a single
