[PATCH 07/12] ASoC: Intel: avs: Set max DMA segment size

[Cezary Rojewski]

From: Amadeusz Sławiński <amadeuszx.slawinski at linux.intel.com>

Apparently it is possible for code to allocate large buffers which may
cause warnings as reported in [1]. This was fixed for HDA, SOF and
skylake in patchset [2], fix it also for avs driver.
