Subject: [PATCH 1/1] net: stmmac: rk3588: Allow multiple gmac controller

From: Benjamin Gaignard <benjamin.gaignard@...labora.com>

RK3588(s) can have multiple gmac controllers.
Re-use rk3568 logic to distinguish them.

Fixes: 2f2b60a0ec28 ("net: ethernet: stmmac: dwmac-rk: Add gmac support for rk3588")

This is required to access gmac1, which is the only existing controller
in the rk3588s (slim variant of rk3588).
