ASoC: rt5677: move jack-detect init to i2c probe
This patch moves the code to select the gpios for jack detection
from rt5677_probe to rt5677_init_irq (called from rt5677_i2c_probe).
It also sets some registers to fix bugs related to jack detection, and
adds some constants and comments to make it easier to understand what
certain register settings are controlling.
