samples: direct_test_mode: Fix gppi implementation

[dchat-nordic]

Fix the mismatch in API for nrfx_gppi_ep_attach function.

[Copilot]

Pull request overview

This PR fixes an API mismatch in the nrfx_gppi_ep_attach function calls within the Direct Test Mode sample. The function signature was being used with reversed parameter order, where the event address and channel identifier were swapped.

Key Changes:

• Corrected parameter order in all nrfx_gppi_ep_attach calls to match the proper API signature (event address first, channel second)
