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

Comment for pcf8574_register_update() function was incorrect as it was
probably copied from different driver function.

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.

Some hardware needs to config this delay to write one data block, because
the hardware needs more time to wear leveling and bad block manage.

The implementation of up_perf_*() is in a different static library in nuttx:
Hardware: libarch.a
Software: libdrivers.a (weak function)
Since functions with weak attributes cannot be correctly replaced in multiple static libraries,
this PR will use macros to replace whether the arch supports hardware perf events

- considering simplicity and design assumption, the reset function must work without flaw.
If it fails, there is no way to recover but to reset again. so checking return status does not
bring additional benefit
- There is unnecessary switch inside switch which is making code not too readable
