Subject: [PATCH V1 0/3] Add support for multiple ICE algorithms

Add support for ICE algorithms for Qualcomm UFS V5.0 and above,
which uses a pool of crypto cores for TX stream (UFS Write – 
Encryption) and RX stream (UFS Read – Decryption).

Using these algorithms, crypto cores can be dynamically allocated
to either RX stream or TX stream based on algorithm selected.
Qualcomm UFS controller supports three ICE algorithms:
Floor based algorithm, Static Algorithm and Instantaneous algorithm
to share crypto cores between TX and RX stream.

Floor Based allocation is selected by default after power On or Reset.
