rpi5: set androidboot.boot_devices for by-name partition mounts

Browse Source 
Mirror of the rpi4 fix. First-stage init only creates /dev/block/by-name/*
symlinks for partitions on a declared boot device, and our fstab mounts
by-name. RPi5 USB is on the RP1 chip behind the internal PCIe and RP1's xHCI
is a platform device, so init matches at the .usb node (deeper than RPi4's
VL805). List NVMe (external PCIe) and the RP1 USB controllers; exact-match set
makes extra entries harmless. To be verified/trimmed against an RPi5 serial log.
