loadb: create file
Allow loadb and loady to create file if file not present. This will allow for downloading a file to filesystem and cp or doing other operations on the same. Making this as an option instead of a default behavior ensures that users intend to create file when they use -c option Signed-off-by: Nishanth Menon <x0nishan@ti.com>
