usb: dwc2: Use platform endianness when accessing registers
This patch switches calls to readl/writel to their dwc2_readl/dwc2_writel equivalents which preserve platform endianness. This patch is necessary to access dwc2 registers correctly on big-endian systems such as the mips based SoCs made by Lantiq. Then dwc2 can be used to replace ifx-hcd driver for Lantiq platforms found e.g. in OpenWrt. The patch was autogenerated with the following commands: $EDITOR core.h sed -i "s/\<readl\>/dwc2_readl/g" *.c hcd.h hw.h sed -i "s/\<writel\>/dwc2_writel/g" *.c hcd.h hw.h Some files were then hand-edited to fix checkpatch.pl warnings about too long lines.
