Subject: [PATCH v6 1/2] arm64: dts: qcom: sm8650: extend the register range
 for UFS ICE

From: Gaurav Kashyap <quic_gaurkash@...cinc.com>

The Inline Crypto Engine (ICE) for UFS/EMMC supports the Hardware Key
Manager (HWKM) to securely manage storage keys. Enable using this
hardware on sm8650.

This requires us to increase the register range: HWKM is an additional
piece of hardware sitting alongside ICE, and extends the old ICE's
register space.
