    i2c-ali1563: Fix device initialization · 849be516

    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.
