[PATCH] gpiolib: acpi: Fix gpio count with string references

[Alban Bedel]

Since commit 9880702d123f2 ("ACPI: property: Support using strings in
reference properties") it is possible to use strings instead of local
references. This work fine with single GPIO but not with arrays as
acpi_gpio_package_count() didn't handle this case. Update it to handle
strings like local references to cover this case as well.
