From: Gaurav Kashyap <quic_gaurkash@xxxxxxxxxxx>
The Inline Crypto Engine (ICE) for UFS/EMMC supports the Hardware Key
Manager (HWKM) to securely manage storage keys. Enable using this
hardware on sm8550.
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.
NOTE: Although wrapped keys cannot be independently generated and
tested on this platform using generate, prepare and import key calls,
there are non-kernel paths to create wrapped keys, and still use the
kernel to program them into ICE. Hence, enabling wrapped key support
on sm8550 too.
