vfork use waitpid hang father process,
but waitpid release child processs information by default.
So when user call wait, it return errno 10.

The class device only handles descriptor information specific to the class,
and shared descriptor information is passed through parameters and
handled by the composite driver.

Create bmi160_base.h, bmi160_base.c bmi160_uorb.c files, the bmi160_base file stores
public function interfaces, and the bmi160_uorb file stores functions related to the
uorb framework. Switch the character interface and UORB interface through the
macro CONFIG_SENSORS_BMI160_UORB.

This option enables architecture-specific memory copy for dynamic code loading.
For example, Ambiq has MRAM regions for instruction which can't load by
the memcpy directly.

Load all sections to LMA not VMA, so the startup code(e.g. start.S) need
relocate .data section to the final address(VMA) and zero .bss section by self.
For example, SiFli and Actions: Background: Device with small sram,
Bootloader run in sram and psram, need boot to Application, with memory overlap
and without XIP. VMA of .data is in "psram" and LMA in "rom", if not enable
`ELF_LOADTO_LMA`, ELF loader will load the section to VMA (will fill bootloader
itself).

This commit adds basic support for electrically isolated 8 bit expander.
The expander communicates with the MCU via SPI interface. Both single
and multiple pin read are supported.

Move SCU-specific ak09912 sensor into spresense board layer.
Rename a function name to register SCU sensor driver
from ak09912_register to ak09912_scu_register.
Channel polarity can now be set with PWMIOC_SETCHARACTERISTICS ioctl
command as field cpol was added to pwm_info_s structure. This way the
polarity can be easily set from application layer for each channel
apart and also can be change on at runtime if required (although this is
not likely).
Helper defines were also added to simplify the definition of low and high
polarity level. Architecture level should take care of writing the
polarity to correct MCU registers.

Allows the debug behavior to be specified as part of the board, architecture or chip configuration. This is useful when using out-of tree custom board configurations.
Documentation for PWMIOC_SETCHARACTERISTICS ioctl command mentioned
that this command will neither start nor stop the pulsed output. This
however is incorrect as PWMIOC_SETCHARACTERISTICS command leads to
pwm_start() function which starts the pulsed output.
While this might not be the correct behaviour (I would probably welcome
the option to set PWM characteristics without starting the pulsed output)
it is the way the PWM driver is coded for many architectures. Future
enhancement might be to add function pwm_setchar() for example to just
set characteristics without starting the PWM output.

Some driver like virtio-net can offload fragmented IOBs, so an interface
to support this feature is needed.

- Fix `ip6_map_ipv4addr` and `ip6_get_ipv4addr` macro to work under
different endianness.
- Use `iob_reserve` instead of `iob_trimhead` in `udp_datahandler`.
- Because we may set `sockaddr_in6` into IPv4 header, which causes
`offset` become negative. `iob_reserve` can hold this case while
`iob_trimhead` cannot.
- Select IPv4 domain in send case.
