RP2040 is now certified to run at 200Mhz clock instead of 133Mhz (125Mhz from SDK was used).
https://github.com/raspberrypi/pico-sdk/releases/tag/2.1.1

So, if no one minds, this is an overclock to the new allowed ones.

New perf values:
arm-none-eabi-gcc (Arch Repository) 14.2.0

rp2040	  ticks
1 stepper 3  ~ 4000K
3 stepper 14 ~ 2571K

Which allows us to place it aside with STM32F446 on the benchmark page.

This patch has been only tested on the development board.
