The previous driver implementation aimed to maximize the amount of
filters, which resulted in a fairly complex implementation.
Background: The bxCAN assigns a number to the filters in the order they
appear in the filter banks. This number is used to match messages in
the FIFO with their filter. If the scale or mode of a filter bank is
changed, all following filter numbers get an offset and the assigned
callbacks have to be shifted accordingly.
The required additional space for the shifting operations resulted in
non-deterministic behaviour and the maximum number of filters could not
be determined at compile-time, which made several tests like
tests/drivers/can/api fail.
This implementation uses a more simple but reliable approach for
filtering and and reserves fixed space for extended and standard ID
filters in the available banks (configurable via Kconfig).
The list mode is not used, which may reduce the total number of usable
filters depending on the application.
The maximum amount of filters is 14 if all filters use ext. IDs,
28 if all use std IDs and something in between if mixed IDs are used.
Also see issue #47986 for more detailed background information.

Obtain machine timer addresses and IRQ from Devicetree. Note that driver
supports multiple compatibles because mtime/mtimecmp registers are
implemented in different ways depending on the vendor. That means
Devicetree representations can be slightly different and so code to

Soft resetting a STM32 device currently does not reset the USB
connection, which causes a few problems: The endpoints do not respond
anymore, and within zephyr any kind of status information like
CDC_SET_CONTROL_LINE_STATE is also missing as they are not
re-negotiated.
This is fixed by stopping the USB device from zephyr side, right after
initialising the USB device.

The HAS_I2C_DW was to limit Kconfig visibility to only platforms
that utilize the I2C DW IP. The Kconfig for I2C_DW depends on
DT_HAS_SNPS_DESIGNWARE_I2C_ENABLED which will cause the same
visbility limitation to only platforms that have I2C DW devicetree
nodes. Thus we can remove HAS_I2C_DW and its references.

When configuring PLL, we should first make sure we're not running on PLL,
and if running on PLL, first switch to a fixed clock before proceeding
with PLL configuration.
Current code is doing the switch systematically which is not useful as
default startup case is to use MSI as sysclk source.
So add a test before doing this switch.

hardware block. The current driver supports the clock gating capability
for the hardware IPs embedded in the SOC. Each clock source has a
clock ID that can simply map to a bit in syscon registers CLK_STOP_CTRL0
(group 0) or CLK_STOP_CTRL1 (group 1). There are some clock sources
that don't have associated clock gating control, which are always on,
