Commit Message

Luan Icaro Pinto Arcanjo Aug. 9, 2024, 9:01 p.m. UTC 
From: LipArcanjo <luanicaroarcanjo@gmail.com>

All dce command_table_helper's shares a copy-pasted collection
of copy-pasted functions, which are: phy_id_to_atom,
clock_source_id_to_atom_phy_clk_src_id, and engine_bp_to_atom.

This patch removes the multiple copy-pasted by creating a
common command table and make the command_table_helper's calls
the functions implemented by the common instead.

The changes were not tested on actual hardware. I am only able
to verify that the changes keep the code compileable.
