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

ARM: mvebu: fix size mask for RAM window ...

The size field in the window control register occupies bits 31:16. So
adapt ARMADA_370_XP_DDR_SIZE_MASK accordingly. This fixes detection of
RAM chips smaller than 32 MiB and so probably doesn't affect any
supported machine.

ratp: only allow bidirectional consoles ...

Ignore requests to switch to RATP mode in input-only or output-only
consoles.

This actually also avoids segfaulting later on:

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 file/fifo consoles ...

barebox_register_console() uses xzalloc which requires the malloc pool
to be initialized, so call it during the second option parsing when
this is already done.

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.
