serial: Set baudrate on boot
Currently, the baud rate is never set on boot. This works ok when a previous
bootloader has configured the baudrate properly, or when the baudrate is set to
a reasonable default in the serial driver's probe(). However, when this is not
the case, we could be using a different baud rate than what was configured.

watchdog: honour hw_margin_ms DT property
Some watchdog devices, e.g. external gpio-triggered ones, must be
reset more often than once per second, which means that the current

the device. Allow any watchdog device to specify such a property, and
then use a reset period of one quarter of that. We keep the current

usb: Keep async schedule running only across mass storage xfers
Rather than keeping the asynchronous schedule running always, keep it
running only across USB mass storage transfers for now, as it seems
that keeping it running all the time interferes with certain control
transfers during device enumeration.
Note that running the async schedule all the time should not be an
issue, especially on EHCI HCD, as that one implements most of the
transfers using async schedule.
Note that we have usb_disable_asynch(), which however is utterly broken.
The usb_disable_asynch() blocks the USB core from doing async transfers
by setting a global flag. The async schedule should however be disabled
per USB controller. Moreover, setting a global flag does not prevent the
controller from using the async schedule, which e.g. the EHCI HCD does.
This patch implements additional callback to the controller, which
permits it to lock the async schedule and keep it running across
multiple transfers. Once the schedule is unlocked, it must also be
disabled. This thus prevents the async schedule from running outside
of the USB mass storage transfers.
