Update patch for sunxi-dev 4.5 - bananapi-r1 switch

This patch modifies the sunxi-dev/bananapi-r1-switch-driver.patch to work with

the changed phy/mdio interface in 4.5.
It was also necessary to revert commit

88f8b1bb41c6208f81b6a480244533ded7b59493 "stmmac: Fix 'eth0: No PHY found' regression"

because it breaks networking on all my sun7i-a20 boards (bananapi, cubietruck, and bananapi-r1)
