Martin Blumenstingl d374e0346e lantiq: 5.15: refresh patches
0001-MIPS-lantiq-add-pcie-driver.patch needs to drop
MODULE_SUPPORTED_DEVICE because that macro is gone on newer kernels.

Add checks for copy_{to,from}_user in
0008-MIPS-lantiq-backport-old-timer-code.patch which is now mandatory.

0705-v5.13-net-dsa-lantiq-allow-to-use-all-GPHYs-on-xRX300-and-.patch
get dropped because it's a backport from Linux 5.13.

All other patches are refreshed.

Subject: [PATCH 2/2] 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.
