The functions probe_kernel_write() and probe_kernel_read() do not modify
the src pointer. Allow const pointers to be passed in without the need
of a typecast.

Blackfin needs it own arch specific probe_kernel_read() and
probe_kernel_write().

This was moved out of the kgdb code and into the
arch/blackfin/maccess.c, because it is a generic kernel api.

The arch specific kgdb.c for blackfin was cleaned of all functions
which exist in the kgdb core that do the same thing after resolving
the probe_kernel_read() and probe_kernel_write().  This also
eliminated the need for most of the #include's.
