ipq40xx: wpj428: fix missing MDIO GPIO reset and pinmux
The bootloader does not always initialize the MDIO pins before booting
Linux. E.g. on version "U-Boot 2012.07 [Chaos Calmer 15.05.1,r35193] (Jul
25 2017 - 11:36:26)" this is the case when booting automatically without
activating the U-Boot console.
Without this change, the kernel boot will complain about missing PHYs:
libphy: ipq40xx_mdio: probed
ar40xx c000000.ess-switch: Probe failed - Missing PHYs!
libphy: Fixed MDIO Bus: probed
With this change it will work as expected:
libphy: ipq40xx_mdio: probed
ESS reset ok!
ESS reset ok!
libphy: Fixed MDIO Bus: probed
