that these variables are only used for information purposes.
When logging is <INFO then the variables aren't utilised at all.
To fix this we're removing the variables completely and using

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.

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.

with symbol aliases were added.
This patch removes the cc32xx related fixup file
definitions, except for those used additionally outside

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.

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.
