zynq: fix /dev/pl
prevent double sleep():
callers to sleep() need to be serialized as there can only
be one process sleeping at a time. plrlock and plwlock do
this.
wait for dma to complete in plwrite():
we have to wait for the dma to complete before touching
plbuf again.
maintain COPEN flag in archopen()/archclose():
when open fails because it was in use, clear the COPEN
flag, so archclose() wont screw stuff up.
