[v6] arm64: dts: qcom: extend the register range for ICE on sm8[56]50

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

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.

I see mentions of this being a bit longer, any reasons not to stretch
it to full size?
