target/riscv: define register printers

`riscv_debug_reg_to_s()` can be used to decode register value. If the pointer to buffer is `NULL` it does not print anything, just returns the length of the string. The format is: `<register_value> { <field_name>=<field_value_name or field_value>, ..., }` e.g: `0x400382 { version=2, confstrptrvalid=invalid, hasresethaltreq=0, authbusy=ready, authenticated=true, anyhalted=1, allhalted=1, anyrunning=0, allrunning=0, anyunavail=0, allunavail=0, anynonexistent=0, allnonexistent=0, anyresumeack=0, allresumeack=0, anyhavereset=0, allhavereset=0, impebreak=1, stickyunavail=current, ndmresetpending=false, }` `0x321009 { regno=0x1009, write=arg0, transfer=enabled, postexec=disabled, aarpostincrement=disabled, aarsize=64bit, cmdtype=0, }` Change-Id: I63733d8d36385d89ca15de1a43139134bc488c4f Signed-off-by: Evgeniy Naydanov <[email protected]>
