samus: Fix codec interrupt and add GPIO defines
The codec interrupt needs to come from codec GPIO1, so use the HOTWORD_DET GPIO as the codec IRQ and the DSP_INT as the wake.The This means codec interrupt is GPIO46 which is PIRQO and should be interrupt 30. Also add GPIO defines for the GPIOs attached to the codec itself. These are defined by index, and I used the same "jack detect" and "mic present" indices that were used in baytrail. The codec interrupt to the host is added at index 2 and the hostword detect interrupt to the host is added at index 3. These can be changed as we work through the implementation in the kernel driver.
