[PATCH 6/6] arm64: dts: rockchip: Enable CAN controller on RK3588-Tiger-Haikou

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner at cherry.de>

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.
