Todd Broch bec640fad5 samus_pd: Increase HPD IRQ pulse to 2msec. 
Intel DP sees HPD pulse as 2msec < x < 100msec.  While DP spec
mentions pulse widths >250usec as acceptable they aren't recognized by
i915 driver.

CL increases the HPD_IRQ pulse width to 2msec minimum.

BRANCH=samus
BUG=chrome-os-partner:39717
TEST=manual samus + apple hdmi multiport dongle drivers external
screen.
