when the vsync comes, fb drivers should call fb_vsync_pollnotify to notify POLLPRI, so that users can catch the synchronization time of vsync and do something.

When our netstack is replying packets when processing RX, the replied
packets will be sent without considering of TX quota because we don't
want to drop them. Now we may delay them by pushing them to a queue and
send them later, which can always keep quota working.

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.

In mmcsd_cardidentify(), the clock is not enabled before issuing
CMD0, and the clock has been disabled in mmcsd_removed(). It makes
no sense to enable the clock after issuing CMD0, because when CMD0
is issued, it will exit with error due to the clock is not enabled.

According to the eMMC specification, in Backwards Compatibility
with legacy MMC card mode, the frequency of the SD clock must be
0-26 MHZ; in high speed SDR mode, it must be 0-52MHZ. So we should
switch to high speed SDR mode if the clock frequency is higher than
26MHZ.

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.
