Phy drivers and the ulpi interface providers depend on the
registeration of the ulpi bus. Ulpi registers the bus in
module_init(). This could result in a load order issue, i.e.
ulpi phy drivers or the ulpi interface providers loading
before the bus registeration.
This patch fixes this load order issue by putting ulpi_init
in subsys_initcall().
