With all fields deprecated, yet another struct can be removed. Let's do
so and don't forget about any functions or fields tied to its existence.

SKL/KBL and all others have different firmware loading mechanisms, so 
now how is the difference handled?

skl_dsp_fw_ops::load_fw / load_library and friends.
skl-sst.c holds control over CL_DMA (which is implemented in separated 
_cldma files within /skylake) loading mechanism while struct that is 
being removed here - skl_dsp_loader_ops - has been used for APL/ CNL 
only. The SKL equivalent is a stub -> alloc_dma_buf / free_dma_buf which 
are shared across all platforms.

It's quite obvious that with proper design one does not need 12 
functions and that many types to handle just the loading process. 
Removal of these has also learning value - anyone coming to help us with 
/skylake quickly hits the unreadability wall. Clearer the code, lower 
the learning curve.
