Clean up the I2C access functions to avoid fetching the pca955x

Rename some functions and variables to be more consistent and
descriptive.
Separate patch.
Ack.

This can be indented better.
I would add a temporary dev pointer variable and put this on one line.
struct device *dev = &pca955x->client->dev;
dev_err(dev, "%s: reg 0x%x, val 0x%x, err %d\n",
__func__, n, val, ret);
Hm, I still end up having to use two lines for the dev_err function, so
not sure it's worth it?

Is it used once? If more than once, consider a helper for that as well.
Ack.
Thanks for the review!
