The purpose of this commit is to prevent user from
calling usb_enable() twice from different contexes.
If for example user configures composite device with hid
and USB uart console (CONFIG_USB_UART_CONSOLE=y)
then introduced mutex will prevent from calling
usb_enable twice and thus lead to undefined behaviour of
usb driver controller.
usb_enable shall always be called once as it refers to usb driver
and for now only one USB driver instance is supported in Zephyr.
This mechanism ensures that.

The ch pointer is the result of a CONTAINER_OF() operation, so
checking it for NULL is pointless. Additionally, there's no place that
calls this function with chan set to NULL.

Make the channel ops struct const since there really isn't anything
there that needs to change at runtime. The only exception is the L2CAP
shell which was playing with the recv callback, however that can be
fixed by introducing a simple bool variable.
With tests/bluetooth/shell this reduces RAM consumption by 112 bytes
while adding only 16 bytes to flash consumption.

Previously, there were two issues when attempting to use LOG_HEXDUMP_*
from C++:
First, gcc and clang in C mode both allow implicit pointer conversion
by default, but require -fpermissive, which no one should ever use, in
C++ mode. Furthermore, -Wpointer-sign, the warning emitted in C for
convertion between pointers to types of different signedness (e.g. char*
vs u8_t*) is explicitly disabled in Zephyr. Switch the various hexdump
functions to void*, which is guaranteed to work in both languages.
Second, the soon-to-be-standardized C++20 version of designated
initializers requires that the designators appear in the same order as
they are declared in the type being initialized.

Unfortunately there was some changes done to RX TC stats update that

the last user of the deprecated SYS_CLOCK_HW_CYCLES_TO_NS64() macro.

Add a new Kconfig knob, CONFIG_LWM2M_IPSO_TIMESTAMP_EXTENSIONS. This
defaults to n. When enabled, various IPSO objects will by default have
the timestamp resource (5518) added to their representations. This can
be turned off on a per-object basis.
The idea of adding timestamp resources was originally suggested by
Hannes Tschofenig on this OMA page:

Low frequency and high frequency clocks had separate devices
while they are actually handled by single peripheral with single
interrupt. The split was done probably because opaque subsys
argument in the API was used for other purposes and there was
no way to pass the information which clock should be controlled.
Implementation changes some time ago and subsys parameter was
no longer used. It now can be used to indicate which clock should
be controlled.
Change become necessary when nrf5340 is taken into account where
there are more clocks and current approach would lead to create
multiple devices - mess.
