Marvell HW overlay support for Cadence xSPI

Merge series from Witold Sadowski <wsadowski@marvell.com>:

This patch series adds support for the second version of the Marvell
hardware overlay for the Cadence xSPI IP block. The overlay is a hardware
change made around the original xSPI block. It extends xSPI features with
clock configuration, interrupt masking, and full-duplex, variable-length SPI
operations.

These functionalities allow the xSPI block to operate not only with memory
devices but also with simple SPI devices and TPM devices.

Example ACPI entry:
      Device (SPI0) {
        Name (_HID, "PRP0001")          // ACPI_DT_NAMESPACE_HID
        Name (_UID, 0)
        Name (_DDN, "SPI controller 0")
        Name (_CCA, ONE)

        Method (_STA) {Return (0xF)}

        Name (_CRS, ResourceTemplate() {
