On STM32WB and dual-core STM32H7 MCUs, the RNG peripheral is shared
between the cores and its access is protected by a hardware semaphore.
Locking was not performed in the current entropy driver, leading to a
race condition when multiple cores concurrently used the RNG. This
commit implements the necessary logic for locking the HSEM during entropy
generation on multi-core STM32 MCUs. It also reconfigures the RNG in case
the configuration was changed by the other core, as this can happen e.g
on STM32WB MCUs.

Some sockets (UDP sockets at least) do not generate "<N>,CLOSED"
messages when the WiFi network drops. As a result the networking stack
thinks these sockets are still open after the network has dropped, and
after any subsequent reconnections.
This affects the DNS resolver library in particular, which leaves UDP
sockets open permanently by default.
Manually close these sockets when the network drops to ensure a clean
state the next time the network connects.

`esp_close_work` can be queued from the `on_cmd_closed`, which clears
`ESP_SOCK_CONNECTED` and sets `ESP_SOCK_CLOSE_PENDING`, but does no
further work. The receive callback should still be run with no data when
the socket is closed through this mechanism.

Xilinx AXI UART Lite v2.0[1] has the following clause for both RX and TX
FIFO respectively:
When a read request is issued to an empty FIFO, a bus error (SLVERR) is
generated and the result is undefined.
When a write request is issued while the FIFO is full, a bus
error (SLVERR) is generated and the data is not written into the FIFO.
To protect this, we have:
xlnx_uartlite_read_status(dev) & STAT_REG_RX_FIFO_VALID_DATA, and
xlnx_uartlite_read_status(dev) & STAT_REG_TX_FIFO_FULL
but these are not enough for multi-threaded apps. Consider two threads
calling poll_out(), it is always possible for a thread to be swapped out
right after reading the status register, the other thread fill the TX FIFO,
and the original thread is swapped back to write more data to the FIFO
because previously read status doesn't indicate the FIFO is full.
To close this race condition, this commit uses a spinlock for each FIFO.
This ensures that only one thread accesses the FIFO even for SMP cases.
This closes#45302.

in pinctrl_soc.h. Regarding the other pin properties, we will implement

Enabling an eSPI channel (r.g. Peripheral Channel, Virtual Wire Channel,
etc.) during an eSPI transaction might (with low probability) cause the
eSPI_SIF module to transition to a wrong state and therefore response
with FATAL_ERROR on an incoming transaction.
This CL workarounds this issue by clearing the bit 4 of NPCX eSPI

the uart_stm32_init() function to ensure this behavior on startup for
