dptx: Optimize read/write GUID functions to use new remote reads/writes.

Browse source 
The remote read/write functions serve as a wrapper in case the target RX device
is directly connected to the TX (link count total is equal to 1).
These functions may be called instead of the read/write GUID functions doing the
same thing.
