[RFC] Renaming or1ksim BSP

[Hesham ALMatary]

Hi all,

Currently or1ksim BSP images can run on or1ksim, QEMU, jor1k, and/or
any or1k based hardware running on FPGAs. The differences maybe with
some boards running or1k on different frequencies, but almost all of
them run at 50 MHz.

I was thinking of renaming or1ksim to something more generic and maybe
it can be parametrized if needed. What about "or1k-generic"? The
parameters can be the frequency and/or memory size if necessary. Would
appreciate your comments.

Thanks,
