Regarding R5900 CPU, some sources indicate that the Emotion Engine
ISA/ASE was designed by Toshiba and licensed to Sony. Others sources
claim it was a joint effort. It therefore makes sense to refer to
the CPU as "Toshiba/Sony R5900".

Also, remove and "'s" in the line for some other CPU, for the sake
of consistency.

The command's usage:
   dump-guest-memory [-p] protocol [begin] [length]
The supported protocol can be file or fd:
1. file: the protocol starts with "file:", and the following string is
   the file's path.
2. fd: the protocol starts with "fd:", and the following string is the
   fd's name.

Note:
  1. If you want to use gdb to process the core, please specify -p option.
     The reason why the -p option is not default is:
       a. guest machine in a catastrophic state can have corrupted memory,
          which we cannot trust.
       b. The guest machine can be in read-mode even if paging is enabled.
          For example: the guest machine uses ACPI to sleep, and ACPI sleep
          state goes in real-mode.
  2. If you don't want to dump all guest's memory, please specify the start
     physical address and the length.
