From: Woodrow Shen <woodrow.shen@xxxxxxxxxxxxx>

The new Dell laptop with codec 256 can't detect headset mic when headset was 
inserted on the machine. From alsa-info, we check init_pin_configs and need to
define the new register value for pin 0x1d & 0x1e because the original macro 
ALC256_STANDARD_PINS can't match pin definition. Also, the macro ALC256_STANDARD_PINS
is simplified by removing them. This makes headset mic works on laptop.
