Merge branch 'zynqmp-phy-config-optional'
Radhey Shyam Pandey says:
====================
net: macb: Make ZynqMP SGMII phy configuration optional
This patchset drop phy-names property from MACB node and also make
SGMII Phy configuration optional. The motivation for this change
is to support traditional usescase in which first stage bootloader
does PS-GT configuration, and should still be supported in macb
driver.
