If per tick is set to 10ms, it will cause nxsig_usleep(1000) in the
sdio driver to sleep for 19ms, which is much longer than the
expected 1ms, resulting in very low write performance. Add option to
reduce CPU hogging by using sched_yield(), though it may also affect
write performance when the CPU is busy.

Add configuration and driver support for the SSD1681 1.54 inch e-paper display,
including the necessary waveforms and settings for proper operation. This extends
the existing SSD1680 e-paper driver to accommodate the new display module.
The changes involve updates to the Kconfig file for additional configuration options,
modifications to the driver implementation in ssd1680.c to include SSD1681 specific
logic, and updates to the header file ssd1680.h to reflect the added support.

When setting the sample rate (`es8311_setsamplerate`) and the bits
per sample (`es8311_setbitspersample`), check their return value in
`es8311_configure`. Also, this commit ensures that these functions
are called after `es8311_reset` to avoid these values to be set to
the default values.
Check if only one driver is used as console to avoid a non-working console
because a different one is selected and has higher priority than the one we wanted
This adds DRIVERS_VIRTIO_SERIAL_CONSOLE config and related logic to
virtio serial so that it can be used as console device. Note that
due to its dependency on OS services, this console is available late
so it is not proper for debugging too early booting issues.

interfaces to the SHT4X temperature and humidity sensor on an I2C bus.

collection and heating functionality.

When initialising the SJA1000 peripheral on some implementations
(SJA1000_FDTOL), "releasing" the buffer when the Rx buffer is empty
causes a buffer pointer misalignment.
On peripheral initialise, remove the flag to "release" the buffer.
This should be safe for all systems using the SJA1000 CAN controller
as a "reset" to the peripheral clears the Rx FIFO.
