ALSA: hda/tegra: Hardcode GCAP ISS value on T234

The GCAP register on Tegra234 implies no Input Streams(ISS)
supported, but the HW output stream descriptor programming
should start with offset 0x20*4 from base stream descriptor
address. This will be a problem while calculating the offset
for output stream descriptor which will be considering input
stream also. So here output stream starts with offset 0 which
is wrong as HW register for output stream offset starts with 4.
So hardcode the input stream numbers to 4 to avoid the issue
in offset calculation.
