scsi: ufs-mediatek: Support performance mode for inline encryption engine
Some MediaTek UFS platforms support high-performance mode that inline
encryption engine can be boosted while UFS is not clock-gated.
The high-performance mode will be enabled if all below conditions are
well-declaired in device tree,
- Proper platform-specific compatible string which enables the host
capability "UFS_MTK_CAP_BOOST_CRYPT_ENGINE".
- "dvfsrc-vcore" node is available in this platform.
- Required minimum vcore voltage for high-performance mode.
- Clock mux and clock parents of inline encryption engine for both
"low-power mode" and "high-performance mode".
