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

Lantiq driver does not work with autodetected fifo sizes so use ones
from original ltq-hcd driver in dwc2. Other values can be
autodetected.

Add VR9 specific usb initialization bits from ltq-hcd to platform
initialization.
This patch is more of a proof-of-concept than production quality
since the initialization registers are different on other lantiq
platforms.

Some Lantiq SoCs are not able to use buffered writes properly with
Intel command set flash due to the way NOR addresses on EBU are
manipulated. This patch disables buffered writes on those devices.
The only device affected at the moment is ARV4510PW, others use
AMD/Fujitsu command set.

For targets with NO_XIP ltq_mtd->map[i].phys equals -1 and devm_ioremap fails.
Fix this by using pdev->resource[i].start instead.
