[PATCH 2/6] can: rockchip-canfd: add support for the RK3588 variant

[Heiko Stuebner]

From: Heiko Stuebner <heiko.stuebner@xxxxxxxxx>

The RK3588 SoC uses a variant of this controller.

>From the start it does not claim to support can-fd in any part of the
documentation, so it seems that is still broken.

Further errata will be enabled in subsequent patches, with more
in-depth explanation.
