[Fix] For the usb host issue, it adds a fix by setting the usb dma bounce buffer under 1G. [Test Case] some users and I alreaady tested the armhf and arm64 kernel on pi4 and pi3 boards, the usb host worked well and no other regressions introduced. [Regression Risk] Low, these patches are from the github which is the pi official kernel repository. And we already tested armhf and arm64 kernel on pi4/3 boards. The rpi kernel of https://github.com/raspberrypi/linux.git has been updated, for the branch of rpi-5.3.y (Eoan kernel base on this branch), there are 107 new patches merged, we also need to merge those patches to Eoan kernel.
