This commit removes the y-selection of the `CONFIG_PINCTRL` Kconfig option
in FE310-based boards defconfig files.
It also makes drivers used in FE310 y-select `CONFIG_PINCTRL` if pinmuxing
is needed.

For code clarity, this commit adjusts the use of `return` statements
in functions with a void return type as follows:
- Transform `return foo();` into separate statements:
`foo();`
`return;`
- Remove unnecessary `return` statements when
they don't affect control flow.

Extracted common SPI RTIO operations from the spi_mcux_lpspi driver
into spi_rtio, which should be common across RTIO drivers.
Tested with spi_loopback with and without CONFIG_SPI_RTIO. Ran on
mimxrt1010_evk.
Also, verified the other SPI RTIO driver (spi_sam) is not broken by
these changes (tested building for target: robokit1 with the same
conditions as above).

As a step to make them common code: spi_rtio.c.
Verified this refactorization builds and passes spi_loopback, both with
CONFIG_SPI_RTIO enabled, as well as disabled. Tested on mimxrt1010_evk.

After testing the flexio spi_loopback on the ke1xz platform,
it is found that the master transfer and receive are not
synchronized. So add loop code to wait for the master transfer
to complete for frdm_ke17z and frdm_ke17z512 platforms.

Fixes division by zero exception when SPI is configured to operate in mode3
whit CS controlled by software.
Such exception occurred because data->dfs is listed as the denominator in
a division inside the spi_esp32_transfer() function which is called from
spi_esp32_configure() (before assigning a value to data->dfs) inside
transceive() in the condition where mode 3 is chosen as the SPI operating
mode and the chip select is configured to be software-controlled.

This driver could end up doing a great deal of work inside the ISR when
large SPI transfers were in use, which could cause significant IRQ
latency. For the normal, non-async SPI transfer case, use events to
signal the calling thread to complete the work rather than performing
FIFO transfers inside the ISR.

Add an optional DT property to specify the size of the RX/TX FIFO
implemented within the SPI core. The property name used is the same one
used by Xilinx's device tree generator.
When the FIFO is known to exist, we can use the RX FIFO occupancy register
to determine how many words can be read from the RX FIFO without checking
the RX FIFO empty flag after every read. Likewise with the TX FIFO, we can
use the FIFO size to avoid checking the FIFO full flag after every write.
This can increase overall throughput.
