Aleksander Jan Bajkowski 5ca8a4a03a lantiq: backport latest upstream patches
Backport patch that fixes memory disclosure in packet padding.
The downstream driver supports statistics, so when a packet
cannot be padded the statistics of dropped packets are incremented.
The other patches do not introduce any functional changes.

Subject: [PATCH] usb: dwc2: add support for other Lantiq SoCs
The size of the internal RAM of the DesignWare USB controller changed
between the different Lantiq SoCs. We have the following sizes:
Amazon + Danube: 8 KByte
Amazon SE + arx100: 2 KByte
xrx200 + xrx300: 2.5 KByte
For Danube SoC we do not provide the params and let the driver decide
to use sane defaults, for the Amazon SE and arx100 we use small fifos
and for the xrx200 and xrx300 SCs a little bit bigger periodic fifo.
The auto detection of max_transfer_size and max_packet_count should
work, so remove it.
This patch is included in OpenWrt for many years.
