Subject: [PATCH v3 4/4] net: phy: realtek: cleanup code

This patch cleans up the drivers code by:

- using a consistent way to reference functions
- removing unused macro-definitions
- removing unnecessary new-lines
- making ack_interrupt functions shorter.

Changes in v3:
* don't use the '&' to reference functions (pointed by Sergei Shtylyov)

Changes in v2:
* separated patch (pointed by Francois Romieu and Sergei Shtylyov)
* make functions shorter (pointed by Sergei Shtylyov)
