UDC API handlers and DWC2 driver thread share not only software
constructs, but also the underlying hardware. Ensure that any UDC API
call is not preempted by DWC2 driver thread (and vice versa) by
acquiring the lock in thread handler.

When the queue is full, all messages posted inside interrupt handlers
are simply dropped. This problem can be remedied by having the message
queue large enough, but determining the maximum number of messages that
can ever be posted in the system is really complex task.
Hopefully in DWC2 driver there is finite number of events that have to
be processed inside thread handler. Therefore it is unnecessary to
determine the maximum queue size for the events if the events are posted
to k_event object instead of send to k_msgq object.
Use combination of three k_event structures to handle all possible event
sources. This not only guarantees by design that no event will be lost,
but also slightly reduces the memory usage.

The STM32 DMA driver can provide interrupts for transfers not yet complete.
However, the current implementation will clear the busy flag for all
interrupts when CONFIG_DMAMUX_STM32 is not enabled. The previous fix for
when CONFIG_DMAMUX_STM32 is enabled should also apply when not enabled.
Also if CONFIG_DMAMUX_STM32 is enabled busy flag will not be cleared when
error interrupts occur.
With this change, the busy flag is only cleared when completion interrupts
in non-cyclic mode or error interrupts occur. These are the cases where
transfer will not continue.

The driver enables the clock of a gpio-port if any of the
pins use the port. This is done by calling pm_device_runtime_get
when a pin is used and pm_device_runtime_put when the pin is not
used anymore.
These calls needs to be balanced. But if a single pin was configured
as GPIO_DISCONNECTED multiple times, every time pm_device_runtime_put
was called.
This caused the clock of the port to be stopped and therefore also
other pins on the same port stopped working.
This commit fixes this by keeping track of which pin on a port
has requested the clock and only call pm_device_runtime_get or
pm_device_runtime_put when the clock-request for the specific pin
changes.

The I2C transfer API has been recently changed to always automatically
set a STOP on the last message, which was well documented but
implemented only by few drivers.
Unfortunately, while documented, this is a change in the current
behavior and it turns out that some applications depended on it for some
complex operations.
Add a flag to temporarily restore the old behavior, buying time to fix
the application code depending on this.

Add bool value that stores the CC change information received in
the interrupt of TCPC alert line. In sink role when in disconnected
state, polling the CC lines causes the chip to be awaken from sleep
mode increasing the power usage. When partner is connected, or any
other CC lines change happens, the chip informs about it with alert.
It can be cached and used instead of asking the chip directly.
