Passing stmmac_priv to some of the callbacks allows hwif implementations
to grab some data that platforms can customize. Adjust the callbacks
accordingly in preparation of such a platform customization.

This patch (and the following patch) are replacements for
https://lore.kernel.org/netdev/20230320204153.21736840@kernel.org/
as was requested. Hopefully I was understanding the intent correctly :)

Changes since v2:
    * New, replacing old wrapper approach

Hi Andrew,

Rather than maintaining these macros can we just get rid of them?
I'd be surprised if things aren't nicer with functions in their place [1].

f.e., we now have (__priv, ..., __priv, ...) due to a generalisation
      that seems to take a lot more than it gives.

Thanks for the pointer. I think that makes sense, I'll take that
approach for these functions (and maybe in a follow-up series I'll
tackle all of them just because the lack of consistency will eat me up).

Sorry for the delay, had some issues around the house that became
urgent.

Thanks,
Andrew

I tried taking this approach for a spin, and I'm not so sure about it
now!

1. Implementing the functions as static inline requires us to know
   about stmmac_priv, but that's getting into circular dependency land
2. You could define them in hwif.c, but then they're not inlined
3. There's still a good bit of boilerplate that's repeated all over
   with the approach. Ignoring 1 above, you get something like this:

static inline int stmmac_init_chan(struct stmmac_priv *priv,
				   void __iomem *ioaddr,
				   struct stmmac_dma_cfg *dma_cfg, u32 chan)
{
	if (priv->hw->dma && priv->hw->dma->init_chan) {
		priv->hw->dma->init_chan(priv, ioaddr, dma_cfg, chan);
		return 0;
	}
	return -EINVAL;
}

that is then repeated for every function... which is making me actually
appreciate the macros some for reducing boilerplate.

Am I suffering from a case of holiday brain, and 1-3 above are silly
points with obvious answers, or do they make you reconsider continuing
with the current approach in hwif.h?

Thanks,
Andrew

I'm about to embark to the holiday brain zone.

But before I do I wanted to acknowledge your concerns and that, yes,
it may be easier said than done.
