Subject: [PATCH 4.4 210/268] MIPS: ath79: Fix AR724X_PLL_REG_PCIE_CONFIG offset

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Mathias Kresin <dev@...sin.me>

[ Upstream commit 05454c1bde91fb013c0431801001da82947e6b5a ]

According to the QCA u-boot source the "PCIE Phase Lock Loop
Configuration (PCIE_PLL_CONFIG)" register is for all SoCs except the
QCA955X and QCA956X at offset 0x10.

Since the PCIE PLL config register is only defined for the AR724x fix
only this value. The value is wrong since the day it was added and isn't
used by any driver yet.
