This patch adds a module load parameter to enable probing of
non-standard LPC addresses 0x162e and 0x164e when scanning for supported
ISA chips.

shouldn't be required since the BIOS usually takes care
of this.
+* probe_all_addr: bool Include non-standard LPC addresses 0x162e and 0x164e

+ - VIA EPIA SN18000
Note that there is no need to use this parameter if the driver loads without
complaining. The driver will say so if it is necessary.
