ACPI / sysfs: Treat the count field of counter_show() as unsigned
The count field is an unsigned 32bit value, and the
counter_show() function should also treat it as a unsigned
value.
Otherwise the counter may show negative number as we found on a
machine:
...
gpe23: 0 invalid
gpe24: -2071733 enabled
gpe25: 0 invalid
...
gpe_all: -2070980
sci: -2070949
