[PATCH] gpu: nova-core: require little endian

[Eliot Courtney]

The driver already assumes little endian in a lot of locations. For
example, all the code that reads RPCs out of the command queue just
directly interprets the bytes.

Make this explicit in Kconfig.

The current code assumes little endian in a bunch of places. I think we
should either explicitly decide to be generic on endianness or explicitly
decide not to - having some handling sprinkled around in various
locations seems confusing to me.

I believe that currently e.g. `RUST` transitively depends on
!CPU_BIG_ENDIAN, so this is more about making the decision explicit for
nova-core rather than fixing any kind of hole.
