ALSA: Fix for reading RIRB buffer on NVIDIA aza controller with AMD Phenom cpu
When read RIRB buffer immediately after RIRB interrupt received,
sometimes the data will be "0x0". If we wait for some time, the data
in buffer will be correct. This issue only occurred with AMD Phenom cpu.
So we set this "needs_damn_long_delay" flag.
