Trogdor: Enable CONFIG_BOARD_RESET_AFTER_POWER_ON to get correct reset flags
Need this config to save the reset flags across double EC reset on the
first power-on.
On power-on, H1 releases the EC from reset but then quickly asserts and
releases the reset a second time. This means the EC sees 2 resets:
(1) power-on reset, (2) reset-pin reset. This config will
allow the second reset to be treated as a power-on.
BRANCH=None
BUG=b:169188750
TEST=Tested on a Trogdor board that the first power-on has the
"power-on" reset flag.
