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

Upstream commit:
80483c3abf8 ("ARM: qcom: Cleanup/Remove unnecessary board file")
removed all the platform device compatibles stating that:
"This patch removes the unnecessary board file. The generic machine
definition is sufficient for the Qualcomm platforms."

IPQ40xx series has a HW pseudo random number generator built in.
It already has a node in the upstream ipq4019.dtsi so we just need to enable it.
Its driver has been rewritten to use crypto API so we dont have char interface like under 4.14 kernel.

DTC was throwing warnings like this:
image-qcom-ipq4018-jalapeno.dtb: Warning (avoid_unnecessary_addr_size): /soc/spi@78b5000/m25p80@0: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property
image-qcom-ipq4018-jalapeno.dtb: Warning (avoid_unnecessary_addr_size): /soc/spi@78b5000/spi-nand@1: unnecessary #address-cells/#size-cells without "ranges" or child "reg" property
So lets fix this for our downstream boards.
