A device-tree property is already defined to indicate that the internal
PHY should be used with active-low leds, which corresponds to a
specific bit in the dedicated syscon register.

Add support for setting this bit when the property is present.

We know about all the relevant fields in the syscon register so there
is no reason to read it first and modify it.

Build the register from scratch instead, with all relevant fields set.

The Allwinner sun8i EMAC driver uses an implicit switch/case fallthrough
when setting up the MAC/PHY communication protocol, to handle the case
when RMII is requested, but would not be supported by the hardware.

Add our "fallthrough;" statement-like macro before the default branch in
sun8i_emac_set_syscon(), to avoid a warning when GCC's
-Wimplicit-fallthrough warning option is enabled.

Add the compatible string for the emac found on the V3s SoC. The SoC
only supports the internal PHY. There are no (R)MII signals on any pins.

As part of bringing the master branch back in to next, we need to allow
for all of these changes to exist here.

When bringing in the series 'arm: dts: am62-beagleplay: Fix Beagleplay
Ethernet"' I failed to notice that b4 noticed it was based on next and
so took that as the base commit and merged that part of next to master.

This reverts commit c8ffd1356d42223cbb8c86280a083cc3c93e6426, reversing
changes made to 2ee6f3a5f7550de3599faef9704e166e5dcace35.

Remove <common.h> from this driver directory and when needed
add missing include files directly.

Make the "phy-handle" property optional, which allows support
for a fixed-link phy configuration.

Thus if the "phy-handle" is present in a DT, then driver will work as
before. Otherwise, phyaddr initialization will not be necessary,
as it is not needed in case of a fixed-link config.

DM_GPIO is always enable in U-Boot proper for ARCH_SUNXI, and this
driver is never enabled in SPL, so the condition is always true.
