sunxi: dts: Update RGMII phy-mode properties

Commit f11513d99787 ("net: phy: realtek: Add tx/rx delay config for
8211e") made the Realtek PHY driver honour the phy-mode DT property,
to set up the proper delay scheme for the RX and TX lines. A similar
change in the kernel revealed that those properties were mostly wrong.
The kernel DTs got updated over the last few months, but we were missing
out on the U-Boot version.

Just sync in the phy-mode properties from the mainline kernel,
v5.17-rc7, to avoid the breaking DT sync that late in the cycle.

This fixes Ethernet operation on the affected boards.

sunxi: Fix old GMAC pinmux setup

Commit 5bc4cd05d7d4 ("sunxi: move non-essential code out of s_init()")
moved the call to eth_init_board() from s_init() into board_init_f().
This means it's now only called from the SPL, which makes sense for
most of the other moved low-level functions. However the GMAC pinmux and
clock setup in eth_init_board() was not happy about that, so it broke
the sun7i GMAC.

Since Ethernet is of no use in the SPL anyway, just move the call into
board_init(), which is only run in U-Boot proper.

This fixes Ethernet operation for the A20 SoCs, which broke in
v2022.04-rc1, with the above mentioned commit.

not confirmed, it could be related to the fact, that quoting the documentation,
