Add head file fixed link error and remove unused flashing function
---
Changes in v9:
- Remove unused LED blink function
- Include log.h and linux/bitops.h to avoid compile warnings
Changes in v8:
- No code change
- Split out individual driver from Cortina Package 2 patch series
to help streamline acceptence into master
Changes in v7:
- rename OFFSET to SHIFT from macros
- add additinal struct comments
- Reading the DT should really happen in the ofdata_to_platdata method
Changes in v4:
- remove unused macros
- remove cortina prefix from macros
- remove use BSS variable
- further cleanup to meet code style guidelines
- add additinal struct comments
- rename DT blink rate symbol
