tegra124: set safe values for href_to_sync and vref_to_sync
href_to_sync and vref_to_sync are chip specific settings. Currently
they are set to 1/2 of hfront_porch and vfront_porch respectively.
However, to support EDID (CL192730), per David Ung, the safe
values for both are 1 (the same settings as in kernel).
BUG=none
BRANCH=none
TEST=built and booted on nyan.
