Workaround some ACPI BIOSen which break the IO port into multiple
resources. (Note that the correct range is 0x3f7,0x3f0-0x3f5.) Such
devices will be detected as follows:
fdc0: <Enhanced floppy controller (i82077, NE72065 or clone)> port
0x3f7,0x3f4-0x3f5,0x3f2-0x3f3,0x3f0-0x3f1 irq 6 drq 2 on acpi0
To do this, we find the minimum and maximum start addresses for the
resources and use them as the base for the IO and control ports.
