|    ipmi: fix ACPI detection with regspacing

got
[   11.026326] ipmi_si: probing via ACPI
[   11.030019] ipmi_si 00:09: (null) regsize 1 spacing 1 irq 0
[   11.035594] ipmi_si: Adding ACPI-specified kcs state machine

on old system with only one range for ipmi kcs range.

Try to fix it by adding another res pointer.
