gpio: pca953x handles more chips, i2c fault codes
Minor updates to the pca953x GPIO expander driver: handle several more compatible parts, and stop assuming that the I2C layer's return codes are garbage (that's now been fixed).

This driver can also be built as a module. If so, the module
will be called pca953x.
