bnx2x: Apply logic changes for the new scheme

Make the needed changes for the new scheme especially around PHY
initialization, and link detection.
- The get_emac_base function was changed to enable setting different MAC
access setting for each PHY based of external configuration.
- As a part of the dual-media preparation, the save_spirom_version was
modified to accept a PHY specific version address to be saved in the
shmem. This will enable to save more than single spirom version in

different locations.
- The test_link function was changed also as a preparation for the
dual-media upcoming changes
- Duplicate initialization logic was removed from the
link_setting_status and link_initialize functions
