fw: Change ASLR name in MMIO
...
Use _RAM_ADDR_RAND instead of _RAM_ASLR since this is not OS-level
ASLR we're talking about. It's address randomization as seen from
outside of the CPU, not from the process running inside it. Ordinary
ASLR is visible from the CPU.

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.

fw: Remove unusued forever_redflash()

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