Atmel SAM family GMAC Ethernet driver is implementing zero-copy
networking. As a result it has to reserve a defined amount of RX
data net buffers before bringing up the interface. Since net buffer
pool is initialized by the network stack and this driver was bringing
the interface up in its initialization function the driver initialization
was performed, as a workaround, after network stack initialization. It
is not a clean solution. This patch fixes this by bringing the
interface up in interface initialization function. The driver itself
can now be initialized before the network stack is.

Adds basic sensor driver support for the Maxim MAX30101 heart rate
sensor.
This driver does not yet support any sensor triggers such as the data
ready trigger, or runtime changing of sensor attributes.
Default configuration values were taken from the MikroE Hexiwear driver.

Both the string and image rendering may want to take advantage of
scrolling and sequential display capabilities. Consolidate the APIs so
that there's a single one for images (mb_display_image) and a single
one for strings (mb_display_print). Both take a duration parameter for
the per-frame duration as well as a mode parameter which specifies
sequential vs scrolling behavior as well as an optional looping flag.

It is envisaged that this will be used by SoC or board code to make
available fixed purpose memory-mapped i/o registers to the rest of the
system which normally expects to use GPIO devices, e.g. for driving chip
select lines, LEDs or reading button states.
As such, the driver code doesn't provide a kconfig based configuration
mechanism, instead SoC/board code can hard-wire the devices it wants
with something simple like:
GPIO_MMIO32_INIT(misc_reg1, "MISC1", 0x12345678, 0xffffffffu)
Then, for example, if bit N of the register at 0x12345678 is wired up as
an SPI device chip select line, the SPI driver could be configured to
use pin N of the "MISC1" GPIO driver and not need any other board
specific code.

As part of the transition to Device Tree, a temporary
HAS_DTS configuration variable, and a .fixup file per board
with symbol aliases were added.
This patch removes the cc32xx related fixup file
definitions, except for those used additionally outside
the cc32xx drivers.
Since cc32xx has DTS files, and since HAS_DTS will always be true,
it also removes the 'if !HAS_DTS' blocks from the cc32xx Kconfig
files.

Adds a simple driver to access the 5x5 LED display found on BBC
micro:bit boards. The display is so limited that no effort is done to
try to integrate with the existing console (which would likely make
the display unusable). Instead, dedicated mb_display_* APIs are added
that are specific to this display.

Rearming the riscv machine timer is done by first updating the
mtimecmp low value register. If the low value is updated with a
relatively small value, a timer interrupt can be generated while
updating the mtimecmp high value.
To avoid such a spurious interrupt to occur, disable the timer
interrupt while rearming the timer.

The device data structure is statically declared and referenced
on a per-controller basis during driver registration. Unfortunately,
due to using the same name (ddata) to initially declare as used
in individual functions, we accidentally referenced the main struct
by mistake due to a lack of local declaration. Let's prevent that
from happening again by using different name-spaces.

selection of channels. The stream number is provided by the DMA API
through it's 'channel' argument, but the sub-channel (within the
