Subject: [PATCH 3/5] interconnect: qcom: msm8996: Fix regmap max_register values

The device tree reg starts at BUS_BASE + QoS_OFFSET, but the regmap
configs in the ICC driver had values suggesting the reg started at
BUS_BASE. Shrink them down (where they haven't been already, so for
providers where QoS_OFFSET = 0) to make sure they stay within their
window.

Fixes: 7add937f5222 ("interconnect: qcom: Add MSM8996 interconnect provider driver")
