 crd-r3 compatible strings

> With newer bootloader versions the crd-r3 (aka CRD 1.0 and 2.0) is
> identified as a 'piglin' board (like the IDP2 board), instead of 'hoglin'
> Add the compatible strings 'google,piglin-rev{3,4}'. The hoglin entries
> are kept to make sure the board keeps booting with older bootloader
> versions.
>
> The compatible string 'google,piglin' (without revision information) is
> still used by the IDP2 board, which is not expected to evolve further.
