I *can* but I don't want to. Inside the bulk of the stmmac driver,
"priv" is used with struct stmmac_priv. "plat_dat" is used with
struct plat_stmmacenet_data.

Having different parts of the driver use the same local variable
name for different structures is confusing, and has already lead to
errors. Consistency is key. This is called "bsp_priv" in
struct plat_stmmacenet_data, and therefore it should be referred to
as "bsp_priv".

I am not yet going to be doing a big rename, but it *will* come in
time.
