watchdog: i.MX: fix i.MX6 reset ...

According to the Errata ERR004346 (WDOG: WDOG SRS bit requires to be written
twice), add another two writes to ensure there must be at least two
writes happen in the same one 32kHz clock period.
Without this two additional writes, the system will not reset always.

Tested with i.MX6Quad and i.MX6 UltraLite

i.MX/WD: setup the watchdog according to its datasheet ...

From earlier SoCs like the i.MX21 up to i.MX7 their datasheets states
after reset the watchdog timer has to be set first prior enabling the
watchdog itself. This change do it this way.

i.MX: fec: add post PHY reset delay DT property ...

Some PHY require to wait for a bit after the reset GPIO has been
toggled. This adds support for the DT property `phy-reset-post-delay`
which gives the delay in milliseconds to wait after reset.

If the DT property is not given, no delay is observed. Post reset
delay greater than 1000ms are invalid.

gpiolib: Add code to support "active low" GPIOs ...

So far this particular aspect of various DT-bindings has been handled
on a per-driver basis. With this change, hopefully, we'll have a
single place to handle necessary logic inversions and eventually
would be able to migrate existing users as well as avoiding adding
redundant code to new drivers.

gpio-imx: Do not use gpio_set_value() ...

Do not use gpio_set_value() in imx_gpio_direction_output().  We don't
check gpio_set_value's result, so calling imx_gpio_set_value()
directly instead should be as good.

sandbox: fix registering multiple consoles ...

Consoles need to be registered with the "console" device name so that
they are probed by the correct driver. The barebox_register_console()
was already forcing this as it was overwriting the name that was being
passed as argument, but it was failing to provide a unique id for
each new console, so the underlying register_device() would just
return an error when wanting to re-register a device with device name
"console" and id 0.

We remove the unused name parameter from barebox_register_console() as
it is really nowhere used, and also specify DEVICE_ID_DYNAMIC as id,
so that a new unique device id is given to each newly registered
console device.

usb: imx: Only use clock when it exists ...

Fixes: bbe0df9

I assumed all chipidea devices actually have a clock. This is true
when looking at the device tree, but in barebox not all i.MX SoCs
use the clocks provided by the device tree. Most instead use
clkdev_add_physbase() to attach a clocks to devices. For these the
chipidea device does not have a clock.
