("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:4dbc107f46
