drm/i915/skl: Register definitions and macros for SKL Watermark regs
This patch defines SKL specific PLANE_WM Watermark registers. It also
defines macros to get the addresses of different LP levels within a pipe.
v2: Reworked the register definitions and associated macros to make it more
generic and be able to use for_each_pipe in values computation.
Incorporated Damien's review comments and indentation.
v3: Added default values for lines and blocks. Provided mask for blocks.
v4: Prefix intermedidate (internal-only) macros with _ (Ville)
v5: Remove the lines and block defaults value (Ville)
