The cpu is almost always 16Mhz and the serial port is almost always
UART0, so no need to prompt in the normal case.

Now that the internal DWT timer is used for software timers, there is
no need to clock the peripherals at a higher clock speed. Clock all
peripherals at 48Mhz and simplify the clock generation code.

Clearing the watchdog while it is in progress can cause bus stalls on
the SAMD21. It appears that clearing the watchdog on the SAMD51 can
cause lockups of the watchdog device.

These two options don't provide any value and it is causing confustion
with some users. Remove the buttons.

Adds the ability to register a custom/generic heater through a new extra called heater_generic.
This takes a gcode_id that is reported by M105. Adds a new command to set the temperature for any heater using the syntax:
SET_HEATER_TEMPERATURE HEATER=<heater_name> TARGET=<target_temp>

- When using absolute extrusion the gcode position e-axis position is now captured on PAUSE and restored in RESUME with a call to the G92 handler.
- Add a get_status() function that returns a dictionary with an 'is_paused' key.
- Do not allow consective calls to PAUSE or RESUME to exectue. Also do not allow a RESUME to executed without a previous PAUSE.

The sram matrix configuration is, bizarrely, configured with a slow
default. It will typically add an extra wait state to every memory
access. Set the matrix sram controller to improve the performance.

Avoid using the "low-level" library timing utilities. This is in
preparation for using SysTick as part of the timer implementation.

The ARM CortexM3 (and later) chips almost always have a 32bit timer in
the "Debug and Watch Trace" (DWT) unit which resides within the cpu
core itself. This timer is generally faster to access than timers
located on the chip's peripheral bus. When combined with the standard
ARM SysTick timer it provides a (generally) portable mechanism to
implement Klipper's software timer mechanism. It's generally also
faster than using the vendor specific timers.

Commit f4d323ad changed the handling of the self.speed variable, and
it inadvertently changed the default startup speed. Return to the
default of 25mm/s.

In the normal case, a regular pin_up command should be sufficient to
raise the probe. (Should the regular pin_up fail, the code can issue
a "reset" command during the retry.)
