drm/i915: Use POSTING_READ in lcpll code
If we don't use the return value of a mmio read our coding style is to
use the POSTING_READ macro. This avoids cluttering the mmio traces.
While at it add the missing posting read in the lcpll enable function
that Paulo spotted.
v2: Drop the _NOTRACE changes, tracing such wait_for loops in the modeset
code might actually be rather useful!
