If the process does an exec() (or fork, or..) all descriptors are kept
open by default, unless O_CLOEXEC is set for them.
(This default behaviour is usefull for stdin/out/err so that new process
is kept connected to them, but it is very rare for it to be usefull for
any other descriptor)
In general this leads to descriptors being kept open unnecessarily,
which either will block other process from using them (for example
if the child survives the parent but it does something else while keeping
a port open).
Or for a "leak" which unnecessarily uses descriptors and memory in the
child process.
Let's ensure we do not leak it for this component as we do not need it.

Fix the check in dwc2_unset_dedicated_fifo() that wrongly included the
current endpoint when testing for higher FIFOs. This caused false
warnings and early returns.
Use ~BIT_MASK(ep_idx + 1) to only test FIFOs above the current EP.

This version is based on the CPU LPSPI driver, directly implementing
the submit call following the non-blocking asynchronous pattern.
This has been re-introduced after struggling to keep up with data
streaming applications, which demands reduced and controlled latency,
which for the default implementation (using RTIO workqueue) is not
guaranteed, due to being serviced by a thread-pool vs directly in the
ISR context.
This version includes limited feature-set, yet stress-tested:
- Required both rx-fifo and tx-fifo to be equal.
- 8-byte words supported only.
- SPI Controller-only supported (target mode not included).
- SPI_HOLD_ON_CS only supported with CS GPIOs.

The driver has ignored the first RX buffer. Most likely it has been
modeled for accesses to a SPI flash or similar where the first read data
is not relevant.
This commit makes sure that the driver can work as a universal SPI
master instead.

The dma_stm32_slot_to_channel function is only applicable on the

platforms among the one based on st,stm32-dma-v1.
While checking for !defined(CONFIG_DMAMUX_STM32) is ok to enable this
on STM32Fx, it prevents to disable dmamux on other platforms since
required symbols do not exist.
