alsa-state: Fix mx6 buffer time

When the buffer time is 512000, there are many audio
bitstreams can't be played, like 88.2k/6channles/16b
on sabre_SD and 96k/24b/6channels on sabre_auto.
Because ALSA can't calculate a suitable playback parameter
group (period_size, period_time, period_count, buffer_size,
buffer_count and so on) for these bitstreams.

So update the buffer time to 450000, which will fix the problem.
