i2c-ali1563: Fix device initialization
The i2c-ali1563 initialization looks quite broken to me: * If the I/O space isn't enabled, we forcibly set 3 bits in the PCI configuration space instead of just the one enabling the I/O space. * After that we pretend to check if the write worked, but we don't actually read the new value from the register. * It's probably not a good idea to enable the I/O space if no base address has been set. So I propose the following changes to that part of the driver: * Merge ali1563_enable() into ali1563_setup(). * Check the base address before the I/O space enabled bit.
