You mean native gdb support? I will port native gdb later. 
The reason why I deleted these two functions is that CSKY did not use the remote protocol
provided by GDB long ago, but implemented a set of djp protocols for debugging. At this
time, these two functions are useful. And at the same time, when debugging with gdbserver,
software breakpoints are also inserted and deleted through these two interfaces.
However, the GDB Stubs used by CSKY now use the remote protocol provided by GDB, and
gdbserver also supports inserting and deleting software breakpoints, so these two functions
are no longer needed.
I haven't carefully checked whether native gdb needs these two interfaces, if necessary, add
them later.
