[PATCH 1/7] phy: ti: phy-j721e-wiz: Add SGMII support in wiz driver for J7200

[Roger Quadros <rogerq@kernel.org>]

From: Siddharth Vadapalli <s-vadapalli@ti.com>

Select the same mac divider for SGMII too as the one being used for
QSGMII.

Enable full rate divider configuration support for J721E_WIZ_10G for
SGMII.
