From: Heiko Stuebner <[email protected]> CAN0 is piped through the Q7-connector to the CAN-Header on the Haikou base-board, so enable support for it there. At least on RK3588-Tiger, the CAN clocks default to 99MHz, limiting usable CAN bitrates without skew. Errata documentation mentions 300MHz as the default frequency on RK3568, so replicate this here to allow more bitrates.
