arm/rp2040,rp2350: Use BOARD_XOSC_FREQ for calculating startup delay

Browse Source 
Previously this used a hard-coded value of 12 MHz, but this presumably
should use `BOARD_XOSC_FREQ`. Similarly to how it is done in pico-sdk.

It looks like all boards are currently defined to use 12 MHz XOSC
clocks, so this won't change behavior with any of them.
