The Message Signaled Interrupts (MSI) support has been introduced in UFSHCI
version 4.0 (JESD223E). The MSI is the recommended interrupt approach for
MCQ. If choose to use MSI, in UFS DT, we need to provide msi-parent
property that point to the hardware entity which serves as the MSI
controller for this UFS controller.

Except scaling UFS and bus clocks, it's necessary to scale also the
voltages of regulators or power domain performance state levels. Adding
Operating Performance Points table allows to adjust power domain
performance state, depending on the UFS clock speed.
OPPv2 deprecates previous property limited to clock scaling:
freq-table-hz.

Add bindings for common parts (platform) of Universal Flash Storage
(UFS) Host Controllers in dtschema format.
Include also the bindings directory in the UFS maintainers entry.
