Subject: [PATCH v3 net-next 6/6] net: phy: realtek: create rtl8211f_config_phy_eee() helper

To simplify the rtl8211f_config_init() control flow and get rid of
"early" returns for PHYs where the PHYCR2 register is absent, move the
entire logic sub-block that deals with disabling PHY-mode EEE to a
separate function. There, it is much more obvious what the early
"return 0" skips, and it becomes more difficult to accidentally skip
unintended stuff.

v2->v3: rtl8211f_config_phy_eee() should not contain genphy_soft_reset()
v1->v2: patch is new
