Subject: [PATCH 5.9 157/255] net: phy: realtek: support paged operations on RTL8201CP

From: Heiner Kallweit <hkallweit1@...il.com>

[ Upstream commit f3037c5a31b58a73b32a36e938ad0560085acadd ]

The RTL8401-internal PHY identifies as RTL8201CP, and the init
sequence in r8169, copied from vendor driver r8168, uses paged
operations. Therefore set the same paged operation callbacks as
for the other Realtek PHY's.

Fixes: cdafdc29ef75 ("r8169: sync support for RTL8401 with vendor driver")
