The parameter provided to the `BIT()` macro must be checked so that
the shift operation does not overflow the variable.

The dacx3608 line supports a broadcast register so all configured channels
can output a singular value, simultaneously. This drastically reduces I2C
overhead when using multi-channel control. An API addition was necessary
to support a global broadcast channel number. The API addition does not
break the write_value() implementation for other DAC drivers in the repo.
This change is based on an out-of-tree driver developed internally to
handle this use case.
Alternative to the API change, could be a KConfig option or device tree
entry. Also, no support for the Broadcast channel was added to the
channel_setup() implementation - this may or may not be confusing. I
believe it makes sense to maintain explicit setup calls for each channel
intended to be configured.

Since this DAC is connected via I2C bus the init priority
value must be higher than the default 50 so it can be initialized
later than the bus itself so add a dedicated init config
symbol for that.

Files including <zephyr/kernel.h> do not have to include

In order to bring consistency in-tree, migrate all drivers to the new
prefix <zephyr/...>. Note that the conversion has been scripted, refer
to #45388 for more details.

Refactors all of the DAC drivers to use a shared driver class
initialization priority configuration, CONFIG_DAC_INIT_PRIORITY, to
allow configuring DAC drivers separately from other devices. This is
similar to other driver classes like I2C and SPI.
The default is set to CONFIG_KERNEL_INIT_PRIORITY_DEVICE to preserve the
existing default initialization priority for most drivers. The
exceptions are dacx0508, dacx3608, and mcp4725 drivers which have
dependencies on SPI or I2C drivers and must therefore initialize later
than the default device priority.

The DAC53608 and DAC43608 (DACx3608) are lowpower, eight-channel,
voltage-output, 10-bit or 8-bit digital-to-analog converters (DACs)
respectively. They support I2C with a wide power supply range
from 1.8 V to 5.5 V, and a full scale output voltage range of
1.8 V to 5.5 V. The DACx3608 also includes per channel, user
programmable, power down registers.
