mfd: tqmx86: Specify IO port register range more precisely

Registers 0x160..0x17f are unassigned. Use 0x180 as base register and
update offets accordingly.

Also change the size of the range to include 0x19f. While 0x19f is
currently reserved for future extensions, so are several of the previous
registers up to 0x19e, and it is weird to leave out just the last one.
