drm/i915/wm: move remaining watermark code out of intel_pm.c
Add new files intel_wm.[ch] and i9xx_wm.[ch] under display/ to hold
generic and pre-SKL watermark code, respectively. SKL+ watermark code
has already been split out to skl_watermark.[ch].
Use the _wm.[ch] naming for brevity; we may want to rename
skl_watermark.[ch] later accordingly.
Add new intel_wm_init() to call either skl_wm_init() or
i9xx_wm_init(i915) depending on the platform, the latter comprising of
the remains of intel_init_pm().
Sprinkle in some minor checkpatch fixes while moving the code.
v2:
- Rebase
- Fix copyright year
