Subject: [RFC PATCH net-next 2/8] net: dsa: mt7530: call port 6 setup from mt7530_mac_config()

mt7530_pad_clk_setup() is called if port 6 is enabled. It used to do more
things than setting up port 6. That part was moved to more appropriate
locations, mt7530_setup() and mt7530_pll_setup().

Now that all it does is set up port 6, rename it to mt7530_setup_port6(),
and move it to a more appropriate location, under mt7530_mac_config().

Leave an empty mt7530_pad_clk_setup() to satisfy the pad_setup function
pointer.

This is the code path for setting up the ports before:

mt753x_phylink_mac_config()
-> mt753x_mac_config()
   -> mt7530_mac_config()
      -> mt7530_setup_port5()
-> mt753x_pad_setup()
   -> mt7530_pad_clk_setup()

This is after:

mt753x_phylink_mac_config()
-> mt753x_mac_config()
   -> mt7530_mac_config()
      -> mt7530_setup_port5()
      -> mt7530_setup_port6()
