Subject: [PATCH 4.19 568/639] mailbox: qcom-apcs: fix max_register value

From: Jorge Ramirez-Ortiz <jorge.ramirez-ortiz@...aro.org>

[ Upstream commit 556a0964e28c4441dcdd50fb07596fd042246bd5 ]

The mailbox length is 0x1000 hence the max_register value is 0xFFC.

Fixes: c6a8b171ca8e ("mailbox: qcom: Convert APCS IPC driver to use
regmap")
