Move USB PHYs to a standard arrays for Exynos EHCI/OHCI devices. This
resolves the conflict between Exynos EHCI/OHCI sub-nodes and generic USB
device bindings. Once the Exynos EHCI/OHCI sub-nodes are removed, the
boards can finally provide sub-nodes for the USB devices using generic USB
device bindings.

Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:
Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
Warning (unit_address_format): Node /XXX unit name should not have leading 0s
Converted using the following command:
find arch/arm/boot/dts -type f \( -iname "*.dts" -o -iname "*.dtsi" \) -exec sed -i \
-e "s/@\([0-9a-fA-FxX\.;:#]\+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 \
{/g" -e "s/@0\+\(.\+\) {/@\1 {/g" {} +
For simplicity, two sed expressions were used to solve each warnings separately.
To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace: https://elinux.org/Device_Tree_Linux#Linux_conventions
This will solve also a side effect warning:
Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>"

MFC device can be used without any external hardware dependencies (when
IOMMU is enabled), so it can be enabled by default (like it has been
already done for Exynos 542x platforms). This unifies handling of this
device for Exynos3250, Exynos4 and Exynos542x platforms. Board can still
include exynos-mfc-reserved-memory.dtsi to enable using this device
without IOMMU being enabled.
