Subject: [PATCH AUTOSEL 6.3 23/37] ASoC: Intel: avs: Fix avs_path_module::instance_id size

From: Amadeusz Sławiński <amadeuszx.slawinski@...ux.intel.com>

[ Upstream commit 320f4d868b83a804e3a4bd61a5b7d0f1db66380e ]

All IPCs using instance_id use 8 bit value. Original commit used 16 bit
value because FW reports possible max value in 16 bit field, but in
practice FW limits the value to 8 bits.
