Changes on registers names

[racarla]

The RISC-V Instruction Set Manual Volume II: Privileged Architecture Document Version 20190608-Priv-MSU-Ratified

mbadaddr : -> mtval? The mbadaddr register has been subsumed by a more general mtval register that can now capture bad instruction bits on an illegal instruction fault to speed instruction emulation. (Preface to Version 1.10 - Page 5)

mbase : ? mibase : ? mdbase : ? mbound : ? mibound : ? mdbound : ?

sptbr : -> satp The supervisor virtual memory configuration has been moved from the mstatus register to the sptbr register. Accordingly, the sptbr register has been renamed to satp (Supervisor Address Translation and Protection) to reflect its broadened role. (Preface to Version 1.10 - Page 5)

sbadaddr : stval?

thanks for reading and for the great work done with the simulator!
