Changes for v2:
- make code EHCI-independent
- use udelay() in waiting loop
- mark static functions as static
- naming changes
Changes for v3:
- merge with patch ulpi: add generic ULPI support header file
- rewrite ULPI interface in more functionality-oriented way
Changes for v4:
- add error-checking
- add waiting for completion into ulpi_reset() function
