Subject: [PATCH] ASoC: Intel: Skylake: Send correct size in ipc header for
 large config

To query information from FW we use "Large Config Get" message which accept
arguments in the form of extended params. So we need to send a TX message of
fixed size (8 bytes) to retrieve a large reply. Hence, IPC header should
reflect correct size of TX message for these messages.
