machine: bump rp2350 CPUFrequency to 150 MHz (#4766)

eliasnaur · web-flow · commit b95effbdd799 · 2025-03-01T10:09:53.000-03:00
Leave rp2040 speed bump to 200 MHz for a future change, because it requires bumping the core voltage as well[0]. [0] https://github.com/raspberrypi/pico-sdk/releases/tag/2.1.1
