When enabling "low level options" in Kconfig, selecting a chip that is
20Mhz capable would result in 20Mhz being the default. A 16Mhz speed
is the preferred default, so list that first in the menu.

The FIOSET and FIOCLR registers may not set an initial value if the
pin is not in an output mode. So, use FIOPIN to set the initial
value.

When reducing the maximum speed due to the max_accel_to_decel setting,
move velocity limits must still be propagated. Otherwise, the
trapezoid move planner may produce moves with velocity jumps.

Since the previous config file was laid out only for TMC2208 drivers and was missing most other pins, I made a comprehensive configuration file, with hardware names for all available functionality.

Once a hop is performed, it will only be re-issued if the z-axis has been
moved in the meantime. Usually it is only moved by a z-homing so doing so
will cause safe_z_home to do the hop on the next homing action.
When z-axis is homed, x and y positions are known. When setting this
boolean option, these are set back to their last positions.
Whenever a hop is specified it is re-issued after the Z axis has been
homed. This is especially necessary when a pressure-based probe is used.
Also, the module decides if a hop is necessary, based on either a known
Z position or a flag that is set whenever the motors are disabled.

Previously, when a sercom pin specified the mcu (myname:PIN), it would result in a pin enumeration error.

The usbfs receive buffers must also have space for the 2 byte crc at
the end of a transmission. This fixes an error that could lead to
lost messages from mcu to host (resulting in bytes_invalid increasing
in stats) on the stm32f103.

As per 18e6772010
This lowers the voltage and thus brings the stepper motor temperature to
an acceptable level. Beforehand, motors would get very hot.

The SKR mini E3 is marketed as being for the Ender 3, so it makes
sense for the example electronics config to be more similar to the
Ender 3 config.

R Still missing, also might be somewhat dirty since code is converted
into G1 commands.

It appears the usbotg controller can get confused if the usb irq
handler runs while processing a usb request. Disable usb irqs during
usb processing to avoid this.

Use the XFRC interrupt instead of TXFE. Don't mask/unmask the tx
interrupts during runtime. This fixes some race conditions where a tx
notification may have previously gotten lost.
