We've added the bass speaker support on Acer 8951G by the commit
00066e9733f6 ("Add Acer Aspire Ethos 8951G model quirk"), but it seems
that the GPIO pin was wrongly set: while the commit turns off the bit
to power up the amp, the actual hardware reacts other way round,
i.e. GPIO bit on = amp on.

So this patch fixes the bug, turning on the GPIO bit 0x02 as default.
Since turning on the GPIO bit can be more easily managed with
alc_setup_gpio() call, we simplify the quirk code by integrating the
GPIO setup into the existing alc662_fixup_aspire_ethos_hp() and
dropping the whole ALC669_FIXUP_ACER_ASPIRE_ETHOS_SUBWOOFER quirk.
