It removes the inclusion to hardware.h by hard-coding the physical address of uart port and copying IMX_IO_P2V from hardware.h. Since we will need a common solution, which might use a fixed virtual address for uart port across platforms, we make a copy of IMX_IO_P2V here as a temporary solution to enable low-level debug for imx multi-platform build.
