fw: Change license for use with qemu
This file is also included in at least qemu (GPL-2.0-or-later) besides
tillitis-key1 (GPL-2.0-only) and tkey-libs (GPL-2.0-only) so it's
licensed as GPL v2 or later even if the rest of the project is -only.

fw: Change memory constants to defines
Instead of putting  memory constant into an enum we use defines.

Use the direct memory address instead of ORing constants together to
compute the address.

An enum in ISO C is a signed int. Some of are memory addresses are to
large to fit in a signed int. This is not a problem since we're not
using ISO C (-std=gnu99) but it doesn't look very nice if you turn on
pedantic warnings. Also, if someone would use another compiler which
at least supports the inline assembly we use, but possible not other
GNU extensions, things would probably break.

Use pedantic warnings
Use pedantic warnings but still allow inline assembly, so turn off
language-extension-token warnings.

fw: Remove unusued forever_redflash()
Since we now use assert() and feed the CPU an unimplemented
instruction we have no need for this.
