drm/i915/skl: Read the Memory Latency Values for WM computation
This patch reads the memory latency values for all the 8 levels for
SKL. These values are needed for the Watermark computation.
v2: Incorporated the review comments from Damien on register
indentation.
v3: Updated the code to use the sandybridge_pcode_read for reading
memory latencies for GEN9.
v4: Don't put gen 9 in the middle of an ordered list of ifs
(Damien)
v5: take the rps.hw_lock around sandybridge_pcode_read() (Damien)
v6: Use gen >= 9 in the pcode_read() function for data1.
Move the defines near the gen6 ones and prefix them with PCODE.
Remove unused timeout define (the pcode_read() code has a larger
timeout already).
