[PATCH 1/1] riscv: dts: starfive: Milk-V Mars CM Lite broken-cd

[Heinrich Schuchardt]

The card detect GPIO depends on support by the base board.

Detecting an SD-card did not work for me with a Milk-V Mars CM Lite
mounted on an Waveshare CM4-IO-BASE-A board.

According to [1] SD_SDIO0_CD_GPIO41 is connected to pin 76 reserved.
The Raspberry Pi Compute Module 4 IO Board documentation marks that pin as
reserved. The Raspberry Pi Compute Module 5 IO Board documentation
marks the pin as VBAT.

Remove the cd-gpios definition and add broken-cd.
