Ronald G. Minnich 575e910127 exynos5420: Tighten up displayport timing loops
We were running this loop 100 times with 5 ms delays. Change it
to run 500 times with 1 ms delays, which gives us the same
overall timeout but lets us bail out a bit sooner -- in practice,
at most, 4 ms sooner but every bit counts. Note, however, that
the tighter timing does reduce opportunities for threading. There
is a non-obvious set of tradeoffs on timeouts.

BUG=None
TEST=build and boot with this test and note we still have graphics
BRANCH=None
