RT5670 codec driver and its machine driver for Intel CHT assume the
implicit GPIO mapping on the index 0 while BIOS on most devices don't
provide it.  The recent commit f10e4bf6 ("gpio: acpi: Even more
tighten up ACPI GPIO lookups") restricts such cases and it resulted in
a regression where the headset jack setup fails like:

  rt5670 i2c-10EC5672:00: ASoC: Cannot get gpio at index 0: -2
  rt5670 i2c-10EC5672:00: Adding jack GPIO failed

For fixing this, we need to provide the GPIO mapping explicitly in the
machine driver.  Also this patch corrects the string to be passed to
gpiolib to match with the pre-given mapping, too.
