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.
