Add usb_fs driver so that userspace can directly transfer USB packets
through the EP node. ADB, Fastboot, MTP will use usb_fs, these class
driver only need to provide the descriptors and register the usb_fs device.

The RPMB partition cannot be accessed via standard block layer, but by a set of specific commands: WRITE, READ, GET_WRITE_COUNTER, and PROGRAM_KEY. Such a partition provides authenticated and replay protected access, hence suitable as a secure storage.

In sensor_rpmsg_ioctl, when rpmsg_get_tx_payload_buffer is block,
The rptun thread will continue to process rx_buffers from other cores,
So the proxy may be released in sensor_unadv_handler, then if using
the proxy, It causes a crash.

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

When the system starts up, the hw count may not start counting from 0,
which can cause the processing time of the first oneshot handler to be
too long. Therefore, the current tick value should be set based on the
hw count during initialization.

Whevenever the bit rate is going to be set, it's necessary to first
set the master clock if the underlying device supports it. If it
fails, just return the error code.
According to the struct `mclk_rate_s`, set the default sample rate
to its lowest valid value. This prevents the underlying driver from
setting unsupported values.
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.

A usbdev has only one serial string, so use a unique macro to control it.
For boards that enable board serial string using COMPOSITE_BOARD_SERIALSTR,
PL2303_BOARD_SERIALSTR, CDCACM_BOARD_SERIALSTR, USBADB_BOARD_SERIALSTR,
USBMSC_BOARD_SERIALSTR, and RNDIS_BOARD_SERIALSTR, they need to be replaced
with BOARD_USBDEV_SERIALSTR.

Commit 50a8ec6 broke many mmc devices. Only if the flag
priv->caps & SDIO_CAPS_4BIT_ONLY was set, it migth work.
Without the flag, the mmc clock is never set (mmcsd_widebus()
call is terminated early stopping the clock). This flag
is probably not very generic because most mmc hw support
1, 4 and 8 bit modes.
JEDEC specifies a bus width selection procedure, but it's
not implemented in this mmcsd_sdio.c driver. Thus, it's
not known whether the hw supports 1, 4 anf 8 bit modes or
a combination of them.
However, with priv->caps & SDIO_CAPS_4BIT_ONLY the driver
suddenly assigns priv->buswidth = MMCSD_SCR_BUSWIDTH_4BIT
making it the only way to have the driver working.
Fix this by relaxing the above mentioned restrictions.

This commit adds basic support for electrically isolated 8 bit expander.
The expander communicates with the MCU via SPI interface. Both single

isx019 driver freezes by I2C access in the interrupt context.
This I2C access is intended to stop data output from FPGA.
Delete this I2C access for the following reasons.
- Data output from FPGA does not affect power consumption
- There are no problems in capture restart without data output stop
since restart is done by image data block first.
This commit adds support for galvanic isolated ISO1H812G SPI expander.
Both single pin and multiple pin writes are supported.
