Remove Sun4c, Sun4d and a few CPUs

Sun4c and Sun4d architectures and related CPUs are not fully implemented
(especially Sun4c MMU) and there has been no interest for them.

Likewise, a few CPUs (Cypress, Ross etc) are only half implemented.

Remove the machines and CPUs, they can be re-added if needed later.
