From: T Karthik Reddy t.karthik.reddy@xilinx.com
Currently "script_offset_f" env variable is hardcoded, this variable specifies from which offset of the flash boot.scr should be read/write. As flashes are of different sizes having a fixed offset makes it difficult to load other images into the flash which may overwrite the boot script or cannot utilize the full memory. This current fix creates a new config "CONFIG_BOOT_SCRIPT_OFFSET" which holds the offset address, overwrites the "script_offset_f" variable. Also removed existing variable with default values, as the default values are held by CONFIG_BOOT_SCRIPT_OFFSET
