Description
Please add in __init__.py support for a crystal oscillator running at 12Mhz.
I would like to use on a [WaveShare RP2040-PiZero](https://circuitpython.org/board/waveshare_rp2040_pizero/) with a [WaveShare RS485 CAN HAT for Raspberry Pi](https://www.waveshare.com/rs485-can-hat.htm) which uses a 12Mhz oscillator. This HAT exists in two variants, one with 8Mhz and one with 12Mhz.

Research direction
Start by inspecting __init__.py for the existing crystal-oscillator configuration and how the current 8MHz case is represented. Confirm how the WaveShare RS485 CAN HAT's 12MHz variant should be selected, then verify that 12MHz support works while preserving the existing 8MHz behavior.
