video: tegra: dc: use fixed h_ref_to_sync value for HDMI

use fixed h_ref_to_sync value of 1 for HDMI to fix
HDMI 7-25 video format timing compliance test failure.
Previously fixed values of v/h_ref_to_sync were used for
HDMI IP. But calculated v/h_ref_to_sync values were used
with change http://git-master/r/#/c/554713/ as a part of
bug 1631663 to enable IMP. But this caused 7-25 video format
timings compliance failure. This change fix it using fixed
h_ref_to_sync value as it doesn't affect IMP with acceptance
from hw. More detailed discussion in the bug.

Bug 200129647
