Some devices need their firmware as a set of {address, len, data...}
records in some specific order rather than a simple blob.
The normal way of doing this kind of thing is 'ihex', which is a text
format and not entirely suitable for use in the kernel.
This provides a binary representation which is very similar, but much
more compact -- and a helper routine to skip to the next record,
because the alignment constraints mean that everybody will screw it up
for themselves otherwise.
Also a helper function which can verify that a 'struct firmware'
contains a valid set of ihex records, and that following them won't run
off the end of the loaded data.

Some drivers have their own hacks to bypass the kernel's firmware loader
and build their firmware into the kernel; this renders those unnecessary.
Other drivers don't use the firmware loader at all, because they always
want the firmware to be available. This allows them to start using the
firmware loader.
A third set of drivers already use the firmware loader, but can't be
used without help from userspace, which sometimes requires an initrd.
This allows them to work in a static kernel.

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).

All new crypto interfaces should go into individual files as much
