[PATCH AUTOSEL 5.7 031/388] PCI: brcmstb: Fix window register offset from 4 to 8

From: Sasha Levin

From: Jim Quinlan <jquinlan@xxxxxxxxxxxx>

[ Upstream commit 077a4fa92a615a4d0f86eae68d777b9dd5e5a95b ]

The outbound memory window registers were being referenced
with an incorrect stride offset. This probably wasn't noticed
previously as there was likely only one such window employed.
