ALSA: emu10k1: fix access to Audigy GPIO port
As the register definition clearly states, this is a 16-bit register, yet we did all accesses as 32-bit. The writes in particular would have the potential to clear the TIMER register (depending on how the bus/card actually handles the too long writes). This commit also introduces a separate define A_GPIO which aliases A_IOCFG, which better reflects the distinct usage on E-MU cards. This is done in the same commit to keep the churn down, as we're touching all involved lines anyway.
