firmware: 2sysincludes: Remove byteswap.h and memory.h

These have always been in here but I don't think anyone remembers what
they are for. The firmware library doesn't require endian accesses
(other than the TPM2 marshalling code which provides its own... and I
guess the GPT code isn't actually safe for big-endian systems, which is
probably bad, but a topic for another patch). As far as I can tell, none
of our environments actually define the macros that these two are
guarded by. Let's get rid of them and see what breaks.
