A module is loaded when the path consisting the module is opened.
The module binary(ies) is loaded from file system and cached in
kernel memory for future use. This is downloaded to DSP using DMA
and invoking Load module IPCs
This patch adds support for load/unload module IPCs, DMAing
modules and manging the modules

The size of the pointer to a data structure to send is erroneously
passed to sst_ipc_tx_message_wait() as its tx_bytes argument. It should
be given the size of the pointed skl_ipc_dxstate_info structure instead.
Coincidentally, both the pointer and the structure have the same size of
8 bytes on a 64 bit machine, which "masks" the issue. Compiling for 32
bit reveals the issue more clearly.
Fix the typo for correctness, and to make the code robust to future
evolutions of the skl_ipc_dxstate_info structure size.
This fixes the following coccicheck error:
sound/soc/intel/skylake/skl-sst-ipc.c:641:8-14: ERROR: application of sizeof to pointer

On runtime pm resume, we need to download the firmware, also on
suspend we need to ensure all the interrupts from controller and
DSP are disabled.
Also since we download the firmware on resume, we don't need to do
so on init, so remove that bit

This adds the dsp and ipc initialization for the Skylake platform.
It also requests firmware and uses code loader dma to load it.

The code loader DMA interrupt is received by main interrupt handler which
dispatches it to cldma routines

This adds base SKL IPC library which uses common SST IPC lib.
Here we add definition for IPC types, sending and receiving IPC messages
from aDSP, handling interrupt, sending different types of messages etc
