Subject: [PATCH net-next 08/15] net: sparx5: use SPX5_CONST for constants
 which do not have a symbol

Now that we have indentified all the chip constants, update the use of
them where a symbol is not defined for the constant.

Constants are accessed using the SPX5_CONSTS macro. Note that this macro
might hide the use of the *sparx5 context pointer. In such case, a
comment is added.
