Fixed a bug where unconfigured clocks were connected to the can
interface in the device tree for SAM0, causing the interface to work
incorrectly. Fixed by adding the correct index when calling GENCTRL.
Also, the default divider has been reduced to 6 to allow setting
the bitrate to 500 kbps.
Tested on a canopennode sample on a board with an ATSAMC21E18A
microcontroller.

Adapt MAX32690 driver to use Wrap_MXC_CAN_Init to handle differences
in the MSDK API (see analogdevicesinc/msdk#1306) between the
MAX32690 and MAX32662.
can_driver_api.timing_min required phase_seg1 >= 3 and phase_seg2 >= 2
when configuring CAN bit timing. Both microcontrollers covered by this
driver (MAX32662, MAX32690) support values down to 1 for both of these
timing parameters.
Refer to the docs for registers CAN_BUSTIM1, CANn_BUSTIM1.
Add a can0 node to the MAX32662 dtsi.

Setting the filter registers in master CAN requires initializing master
CAN first. CONFIG_CAN_MAX_EXT_ID_FILTER banks are reserved for IDE
frames. Previously we set FS1R(CAN filter scale register) at init time,
but it is possible that the master CAN is not initialized at that time.
That is when the filter banks are not set correctly, causing that we get
wrong filter_id from slave CAN. This patch fixes the issue by setting
FS1R at the time of initializing master CAN.
Tested on:
STM32F407IGH6 with 2 std_id and 2 ext_id on each of CAN1 and CAN2.

Since the RA2L1 uses the macro "ICU_EVENT" instead of
"ELC_EVENT" (which is currently used) to input into
the IELSR register, the ek_ra2l1 board cannot assign
any interrupts for any driver.
This commit aim to correct the Event macro to input correct
value for IELSR register on all the Renesas SoC by using
"BSP_PRV_IELS_ENUM" macro.

When GPD is enabled, the pinctrl driver enables pin retention if the
peripheral is in the FAST_ACTIVE1 domain. This seems to break CAN, so
make sure retention is not active.
Investigations on why this is needed are ongoing, however, this makes
CAN functional again with some minor changes.

The Atmel SAM0 SoC enable peripherals clocks in distinct places: PM and
MCLK. The old devices had defined the peripheral clock enable bit at PM.
On the newer devices this was extracted on a dedicated memory section
called Master Clock (MCLK). This change excludes the dedicated bindings
in favor of a generic approach that cover all cases.
Now the clocks properties is complemented by the atmel,assigned-clocks
property. It gives the liberty to user to customize the clock source
from a generic clock or configure the direct connections.
All peripherals drivers were reworked with the newer solution.
