I believe you confuse with arch and board. These files are located
inside board. For board/altera/socfpga, its referring to Altera dev kit.
When another vendor, example like Xilinx, fabricated a board with
SOCFPGA chip, then it will have another folder called
board/xilinx/socfpga.

Probably an example will clear your doubt. When the board is fabricated,
the pin mux used will be fixed. You won't need to change it until you
fabricated a new board. 

Hope this info helps.
