raiden_debug_spi.c: Clean up the USB SPI protocol

Perform some clean up the USB SPI protocol 1 prior to adding
protocol 2 to improve consistency and correct minor issues.

* Minor clean up the comments descriptor for the protocol.
  This adds the location of another relevant file, corrects the
  omission of one of the protocol modes, makes the direction
  of the packets explicit, and minor formatting changes.

* Fix typos in constants associated with the retry mechanism.

* Clean declarations to match the EC code formats.

* Updates the error message formatting so protocol V1 closely
  matches the V2 protocol for consistency.

* Minor changes to the structure, moving validation of the
  arguments earlier in the transfer. Overall to keep V1 and
  V2 closer aligned and reduce future changes in the V1 code.
