firmware: make fw->data const
In preparation for supporting firmware files linked into the static kernel, make fw->data const to ensure that users aren't modifying it (so that we can pass a pointer to the original in-kernel copy, rather than having to copy it). Signed-off-by: David Woodhouse <dwmw2@infradead.org>
