c2d2: allow GSC reset in one command
To speed things up when iterating during GSC development let's add an
h1_reset command option to allow to generate a GSC reset pulse in one
invocation.
BRANCH=none
BUG=none
TEST=manual: verified behavior of h1_reset:
'h1_reset pulse' - generate a reset pulse
'h1_reset' - show the current GSC reset state
'h1_reset <0 or 1>' - as expected
