A specific section of the flash on the SiWx917 is reserved for the
Network co-processor (NWP). This zone needs to be delimited in order to
not overwrite it. We then need to use "code-partition" to provide Zephyr
the application code flash location.

Report DMA configuration in the board definitions.
Note the addresses of the DMA buffers are hardcoded in the HAL. So,
these areas have to be declared in the linker file.

The GPIO peripheral on Silabs Series 2 devices is responsible for
allocating analog buses to analog peripherals. Enable support for
this in the pinctrl driver. Since these bus allocations are not
digital pins, introduce a new property silabs,analog-bus for this
purpose.

The GECKO_PIN() macro does not do anything except pass the
argument through unaltered. It only serves to make DeviceTree
files more verbose. It was inconsistently used, make the .dts
files consistent by never using it.
The DBUS pinctrl driver doesn't use the port or location macros
from the gpio_gecko.h header. The pin number macro is the only
other thing defined in this header. Stop including the header on
Series 2 based boards.

Only initialize the HFXO Manager HAL driver if the HFXO is enabled in
DeviceTree, the device uses SYSRTC for timekeeping, and Power Manager
is enabled. HFXO Manager integrates with the Sleeptimer HAL driver for
SYSRTC to autonomously wake the HFXO prior to Sleeptimer wakeup from
deep sleep. It is not needed on devices that don't have HFXO-SYSRTC
integration, and it is not needed if the application doesn't use deep
sleep.
Add missing call to init_hardware() prior to init().

This serves two main purposes:
- change the CPU clock via devicetree nodes
- provide the APB frequency to device drivers via the clock driver
interface
Theoretically this could also support choosing between the available
clock sources, but right now we only support LPOSC0 going into PLL0,
going into AHB.
Turning the PLL back off is also not supported since the only current
use case is to set the PLL frequency, turn it on, and switch the AHB
over to it.
