We should not release context until transfer ends. The code previously
would return from wait_for_completion and then release the context. This
is only supposed to be done in the dma callback except for the case of
error in the transceive call. For async transfer this was most likely
always happening wrong and probably broken for multi threads trying to
access the bus due to this premature release of the context.
Also we should not enable CS and leave enabled in case of error, move CS
enable to after the error check.

Stop the transfer with error if at any point there is some
execution reached where transfer is being set up for 0 length, this can
cause problems where for example eDMA set up with this nonsense 0 length
channels can get an infinite error interrupt.
And this is probably an erroneously crafted transfer request anyways.

If there are HAL definitions available, do these two things:
Ungate the clock for the device from the zephyr driver. Eventually it
would be better to have a clocks property in the LPSPI DT node and get
the resources from there rather than the HAL.
Some platforms require the peripheral to be reset at system level, add
code to do this. Eventually it would be more ideal to have Zephyr
reset drivers for all of the NXP platforms and use DT to describe the
reset resources, but for now we can just do this to get the LPSPI
supported.

Add support for an optional "idle disconnect" feature in the TCA954x
I2C multiplexer. When enabled via the `i2c-mux-idle-disconnect` device
tree property, the driver will disconnect all channels after each
transfer. This helps avoid address conflicts when multiple multiplexers
are present on the same I2C bus.
Even if the I2C transfer fails, the driver will still attempt to
disconnect the channels to ensure the bus is left in a consistent state.
If the disconnect operation itself fails, its error code will be returned
unless the transfer already failed with a different error.
This implementation is inspired by the Linux kernel driver for PCA954x
I2C multiplexers. Special thanks to Ofir Shemesh for valuable suggestion.

Clamp the returned humidity to a non-negative value. This ensure that
the return value is always within the expected range, even if the
calibration parameters are read out incorrectly or corrupted.
This check is applied in the example Bosch driver for the float
conversion case, so there are situations that warrant it.

Setting the filter registers in master CAN requires initializing master
CAN first. CONFIG_CAN_MAX_EXT_ID_FILTER banks are reserved for IDE
frames. Previously we set FS1R(CAN filter scale register) at init time,
but it is possible that the master CAN is not initialized at that time.
That is when the filter banks are not set correctly, causing that we get
wrong filter_id from slave CAN. This patch fixes the issue by setting
FS1R at the time of initializing master CAN.
Tested on:
STM32F407IGH6 with 2 std_id and 2 ext_id on each of CAN1 and CAN2.

Implement `irq_is_pending` in terms of the `irq_rx_ready` and
`irq_tx_ready` function calls.
Using `intstatus` directly results in an implementation that does not
conform to the interrupt driven UART API. Since `intstatus` bits are
only only set when a buffer transitions from full to empty, any calls to
`irq_is_pending` before any bytes have been sent will return 0. This is
problematic since the documented implementation for the API IRQ handler
is:
```
while (uart_irq_update(dev) && uart_irq_is_pending(dev)) {
if (uart_irq_rx_ready(dev)) {
...
}
if (uart_irq_tx_ready(dev)) {
uart_fifo_fill(dev, ...);
}
}
```
If `uart_irq_is_pending` does not return 1 until the first byte is sent,
we never end up pushing data to be transmitted into the `uart_fifo_full`
function.
