Add PWM driver for the Timer peripheral on Series 2.
The TIMER uses the high-frequency EM01 Group A clock, and has
a 16- or 32-bit counter. It supports PWM period and pulse capture
on channel 0, and PWM output on all channels.

Add PWM driver for the Low Energy Timer peripheral on Series 2.
The LETIMER runs at up to 32 kHz and has a 24-bit counter. It
only supports PWM output, it does not support input capture.

Refactor the controller init to use the new init routines the
controller now provides. Instead of using a hardcoded set of
features, the features are now initialized based on Kconfig
values that the application selects.
Add config files under modules/hal_silabs, used by the controller
init routines in the external module hal_silabs to determine which
features to enable based on Kconfig options. This brings the
controller feature configurability to roughly parity with the
Simplicity SDK.

Update the Simplicity SDK HAL for Silicon Labs Series 2
devices to v2025.6.0.
The em_core source file no longer exists in the latest version
of the HAL, and is removed.

Honor Kconfig option `BT_CTLR_TX_PWR_ANTENNA` for limiting the maximum TX
power. The default value for this option is 0 dBm, which means that after
this change the actual TX power is likely lower than before, unless
increased by this option.

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.
