We were using first page of kernel context render state for sharing data
with GuC. While it's justified by the fact that those pages are not used
(note, GuC still enforces this layout and refuses to work if we remove
the extra page in front), it's also confusing (why are we using this
particular page?). Let's allocate a separate object instead.
v2: Drop kernel_context from GuC suspend/resume action handlers (Michel)

Existing code needs some style fixes. To avoid polluting
pure move patch, do it now as separate step.

Function intel_guc_wopcm_size didn't fit well in the old place.
With this move upcoming cleanup will be simpler.

This function gives the status of RC6, whether disabled or if
enabled then which state. intel_enable_rc6 will be used for
enabling RC6 in the next patch.
