    The generic GPIO library directly implement code for acpi_find_gpio()
    which is only used with CONFIG_ACPI. This was probably done because
    OF did the same thing, but I removed that so remove this too.
    
    Rename the internal acpi_find_gpio() in gpiolib-acpi.c to
    acpi_populate_gpio_lookup() which seems to be more appropriate anyway
    so as to avoid a namespace clash with the same function.
    
    Make the stub return -ENOENT rather than -ENOSYS (as that is for
    syscalls!).
    
    For some reason the sunxi pin control driver was including the private
    gpiolib header, it works just fine without it so remove that oneliner.
