Easiest is to change directory one above and then delete it.  The easiest way 
is with rm -r -f which will perform a recursive removal of everything in the 
directory depth first from the bottom up.

  cd ..
  rm -rf fpc_i2cs_cpld  # warning: recursive removal

But you could also delete it using the full path.

  rm -rf ~/fpc_i2cs_cpld  # warning: recursive removal

Those entries are required infrastructure and should not be deleted.
The "." directory refers to the current directory.  The ".." refers to the 
parent directory.  The ".." entry on some classic Unix file systems may be 
unlinked but I don't believe that any current Linux file system allows this.  
This is a restriction imposed by the kernel and not by coreutils.
