This patch will make the driver more readability
The emac has the error and warnings if you run
'scripts/checkpatch.pl -f --subjective xxx' to check.
Let's clean up such trivial details.

Changes in v2:
- As the robot notice the build error since overflow in implicit
constant conversion.

This patch adds the emac device node for rk3036.
We need to let mac clock under the DPLL which is able to provide
the accurate 50MHz what mac_ref need, since that will cause some
unstable things if the cpufreq is working.
