ALSA: emu10k1: fix snd_emu1010_fpga_read() input masking for rev2 cards
Unlike the Alice2 chips used on 1st generation E-MU cards, the
Tina/Tina2 chips used on the 2nd gen cards have only six GPIN pins,
which means that we need to use a smaller mask. Failure to do so would
falsify the read data if the FPGA tried to raise an IRQ right at that
moment. This wasn't a problem so far, as we didn't actually enable FPGA
IRQs, but that's going to change soon.
