Changes from 6.3.2 to main

The onboard USB hub on the BL i.MX8MM doesn't work in U-Boot.
Devices plugged into the USB-C port on a running Linux system on the BL i.MX8MP are not recognised under Linux. They are only recognised if the device was connected during boot-up.
Kirkstone misses support for hardware-accelerated Wayland on i.MX8MP although GPU support has been backported by upgrading Mesa for this platform.
On i.MX8MP there are issues with reading EDID data from some HDMI monitors. This can result in wrong display mode settings.
The package python3-pyqt5 fails to build (see https://github.com/meta-qt5/meta-qt5/issues/585). A workaround is to use the kirkstone branch for meta-qt5 with an older patch release of Qt5.15.
