Aleksander Jan Bajkowski 48c9e55094 kernel: backport upstream Realtek PHY patches
Backport of the latest upstream Realtek PHY patches. WoL uses
devm_pm_set_wake_irq(), so the patch that adds this function
has also been backported.

Changelog:
4465ae435ddc net: phy: realtek: create rtl8211f_config_phy_eee() helper
bb78b71faf60 net: phy: realtek: eliminate priv->phycr1 variable
e1a31c41bef6 net: phy: realtek: allow CLKOUT to be disabled on RTL8211F(D)(I)-VD-CG
910ac7bfb1af net: phy: realtek: eliminate has_phycr2 variable
27033d069177 net: phy: realtek: eliminate priv->phycr2 variable
8e982441ba60 net: phy: realtek: create rtl8211f_config_rgmii_delay()
b826bf795564 net: phy: realtek: fix RTL8211F wake-on-lan support

Tested on Netgear WAX206 with RTL8221B-VB-CG.

Subject: [PATCH 1/2] net: phy: realtek: use genphy_soft_reset for 2.5G PHYs
Some vendor bootloaders do weird things with those PHYs which result in
link modes being reported wrongly. Start from a clean sheet by resetting
the PHY.
