ARM: image: Add option for ignoring ep bit 3
Add option to the booti_setup() which indicates to it that the caller requires the image to be relocated to the beginning of the RAM and that the information whether the image can be located anywhere in RAM at 2 MiB aligned boundary or not is to be ignored. This is useful ie. in case the Image is wrapped in another envelope, ie. fitImage and not relocating it but moving it would corrupt the envelope.
