Linus Walleij 5128f8d445 gpio: name PCA953x gpio chips after device name
Instead of using the name directly from the I2C client
to name the gpio_chip, use dev_name() on the client->dev,
so we get the sometimes more unique device name, as I2C has
a mechanism for naming its devices explicitly in e.g.
board data.

This is a prerequisite for being able to reference
uniquely any I2C GPIO expander defined in a board file
when setting up GPIO descriptor tables.
