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().

Add OS timer implementation making use of the Sleeptimer HAL.
Sleeptimer integrates tightly with the Silabs Power Manager HAL,
and must be used as the OS timer to achieve optimal power consumption
when using the radio.

CMSIS SystemInit is not used in Zephyr. Implement the functionality
that isn't already done by Zephyr startup using soc_prep_hook().
The reason the lack of TrustZone init did not create immediately obvious
issues previously is that SMU faults can only happen if the SMU clock is
enabled.

Rename the Silabs HCI driver to hci_silabs_efr32.c to better indicate what
hardware it supports. Also rename the associated devicetree binding and
Kconfig options to be consistent with the new driver name.

Swap from the deprecated device_init_* functions to clock manager
for clock tree configuration. Populate config headers using
device tree representation of clock tree and oscillator config.

The DC-DC converter was unconditionally initialized with default
settings on Series 2. Add device tree binding and nodes, and guard
call to init function. Map DT options to config header from HAL.

Move the CMakeLists.txt and Kconfig files from the hal_silabs tree under
modules/hal_silabs in the main tree. This also includes all Zephyr shim
code from the hal_silabs tree.
