firmware: generalize reading file contents as a helper

We'll want to reuse this same code later in order to
read two separate types of file contents. This generalizes
fw_read_file() for reading a file rebrands it as fw_read_file().
This caller lets us pegs arbitrary data onto the target
buffer and size if the file is found.

While at it this cleans up the exit paths on fw_read_file().
