4dbc107f4683 ("cmd: gpio: Correct do_gpio() return value") correctly
changed the behaviour of the gpio command to return CMD_RET_SUCCESS or
CMD_RET_FAILURE, but any existing script which expects the return value
to be the pin value is broken by this change.
Reinstate the legacy behaviour for `gpio input` only.
Fixes: 4dbc107f4683 ("cmd: gpio: Correct do_gpio() return value")
