unbind will call the adb_char_on_connect interface to wake up the adbd task,
adbd will then access the adb device and fail to return, at this time it will
close the adb device, we can do the final memory release operation in the
second unbind

Function gpio_lower_half_byname() was added to support registration of
GPIO pin by name as supported for IOexpander. Some of the code is wrapped
in new static function gpio_lower_half_internal() to avoid code
duplication.

This adds support for 16 bit io expander pcf8575. The driver is basically
the same as for pcf8574 however it is for 16 bits instead of 8 bits. Since
pcf8575 and pcf8574 can be both used on the same i2c bus the driver for
pcf8575 is implemented in a different file to reduce the code size
and complexity and to have less if statements in the driver.

Some UART Controllers (Synopsys DesignWare 8250) will trigger spurious interrupts when the Line Control Register (LCR) is set while the UART is busy. This patch provides the option (16550_WAIT_LCR) to wait for UART until it's not busy, before setting the LCR. (16550_WAIT_LCR is disabled by default)
This patch fixes the spurious UART interrupts for the upcoming port of NuttX to StarFive JH7110 SoC (with Synopsys DesignWare 8250 UART). [The patch is explained here](https://lupyuen.github.io/articles/plic#appendix-fix-the-spurious-uart-interrupts)
drivers/serial/uart_16550.c: If 16550_WAIT_LCR is enabled, wait until UART is not busy before setting LCR
include/nuttx/serial/uart_16550.h: Define the UART Status Register (USR) for checking if UART is busy
drivers/serial/Kconfig-16550: Added option 16550_WAIT_LCR to 16550 UART Config, disabled by default
The fd of pipe type is not supported by mmap, mmap() shall failed
with ENODEV. If pipe mmap is not implemented, mmap will forward to
rammap() and get unexpected error.
Implement pipe mmap just return ENODEV. That is to pass LTP posix
test case mmap/23-1.c

W25QxxxJV NOR memories are backward compatible with older Winbond´s
generations and thus can also be supported here. This essentially brings
the support for generic SPI to W25QxxxJV memories as w25qxxxjv.c file only
supports QSPI communication.

wdog_notifier() will be called in _assert to keep the crash scene
as mush as possible, which is useful for debug.
But once disable the watchdog, the hardware watchdog can not reboot
the system too. If a crash happened in the _assert (e.g. the tcb sp
has been corrupted, system will crash again in tack stack dump),
system will crashing forever and can not reboot.
So add a config to disable this feature by default and can be enable
if anyone need it.

When the value that is out of range is specified in ioctl(VIDIOC_S_CTRL) and
ioctl(VIDIOC_S_EXT_CTRLS), returned value should be not EINVAL but ERANGE.
video driver does not support flags member of ioctl(VIDIOC_QUERYCTRL)
and ioctl(VIDIOC_QUERY_EXT_CTRL).
But, ioctl returns with the flags member that has the garbage value.
Add initialization of flags member to avoid return of the garbage value.
