Correctly calculate the value to put in the imx wdog countdown register.
The correct value is seconds*2-1. The code was using just seconds*2, which
led to being off by a half-second -- usually not a big deal, except when the
value was the max (128) it overflowed so zero would get written to the
countdown register, which equates to a timeout of a half second.

Remove a test and early-out which just can't possibly be right. It causes
detach() to do nothing if attach() succeeded, which is the opposite of
what's needed. Also, move device_delete_children() from the end to the
beginning of detach(), so that children won't be trying to make use of the
hardware we're in the process of shutting down.

Properly support the GPIO_PIN_PRESET_{LOW,HIGH} options when configuring
a gpio pin. If neither of the options is specified, pre-set the pin's
output value to the pin's current input value, to achieve glitch-free
transitions to output mode on pins that are pulled up or down at reset
or via fdt pinctrl data.
