net: lan969x: add RGMII implementation
The lan969x switch device includes two RGMII port interfaces (port 28
and 29) supporting data speeds of 1 Gbps, 100 Mbps and 10 Mbps. MAC
level delays are configurable through the HSIO_WRAP target, by choosing
a phase shift selector, corresponding to a certain time delay in nano
seconds.
Add new file: lan969x_rgmii.c that contains the implementation for
configuring the RGMII port devices. MAC level delays are configured
using the "{rx,tx}-internal-delay-ps" properties. These properties must
be specified independently of the phy-mode. If missing, or set to zero,
the MAC will not apply any delay.
