modules-initfs listed 'phy-qcom-snps-eusb2', which does not exist in
kernel 7.2 - the SNPS eUSB2 PHY driver is 'phy-snps-eusb2'
(CONFIG_PHY_SNPS_EUSB2=m). pmbootstrap silently skipped the unknown
name, so the built initramfs shipped only phy-qcom-eusb2-repeater.
Without phy-snps-eusb2, phy@88e3000 (qcom,sm8550-snps-eusb2-phy) never
probes -> the built-in dwc3 at usb@a600000 stays on -EPROBE_DEFER ->
no UDC -> the initramfs can't bring up the USB gadget -> no telnet on
172.16.42.1. Not a panic, but it blocks the whole USB-networking goal.
dwc3 and dwc3-qcom are built-in (modules.builtin), pstore/ramoops too
(rtwo.config's CONFIG_PSTORE_RAM=y stuck).
