Revert "usb: ulpi: defer ulpi_register on ulpi_read_id timeout"

commit b659b613cea2ae39746ca8bd2b69d1985dd9d770 upstream.

This reverts commit 8a7b31d545d3a15f0e6f5984ae16f0ca4fd76aac.

This patch results in some qemu test failures, specifically xilinx-zynq-a9
machine and zynq-zc702 as well as zynq-zed devicetree files, when trying
to boot from USB drive.
