Merge branch 'r8152-save-EEE' 

Hayes Wang says:

====================
r8152: save EEE

v4:
For patch #2, remove redundant calling of "ocp_reg_write(tp, OCP_EEE_ADV, 0)".

v3:
For patch #2, fix the mistake caused by copying and pasting.

v2:
Adjust patch #1. The EEE has been disabled in the beginning of
r8153_hw_phy_cfg() and r8153b_hw_phy_cfg(), so only check if
it is necessary to enable EEE.

Add the patch #2 for the helper function.

v1:
Saving the settings of EEE to avoid they become the default settings
after reset_resume().
