soc/amd/stoneyridge: Define PM USB Enable register
Make #define definitions for PMxEF and replace the hardcoded values.
Note that this doesn't change the current functionality of the source.
The existing code has been propogated from the sb//hudson port, which
seems to attempt to enable 100% of all OHCI and EHCI controllers that
may be present in the system.
