[ALSA] intel8x0 - enable ac97_quirk hp_only for Acer Aspire 3003LCi

Modules: Intel8x0 driver

On my Acer Aspire 3003LCi laptop, the speaker volume is not controlled
by the master control, but by the headphone control. Enabling the
'hp_only' quirk corrects this. The patch below adds this device to the
list of known quirks.
