PATCH 1/1 x86: tangier: Use actual GPIO hardware numbers

The recent commit 03c4749dd6c7
("gpio / ACPI: Drop unnecessary ACPI GPIO to Linux GPIO translation")
in the Linux kernel reveals the issue we have in ACPI tables here, i.e. we must use hardware numbers for GPIO resources and, taking into consideration that GPIO and pin control are *different* IPs on Intel Tangier, we need to supply numbers properly.

Besides that, it improves user experience since the official documentation for Intel Edison board is referring to GPIO hardware numbering scheme.

---

Bin, this is kinda urgent fix. I wouldn't like to have a release with wrong numbering scheme, although there is none users yet, only couple amateurs that are experimenting with the code.
