arm64: versal: Add versal specific cadence ospi driver
Add support for cadence ospi driver for Versal platform. This driver
provides support for DMA read operation which utilizes cadence qspi
driver.
If "cdns,is-dma" DT property is specified use dma for read operation
from cadence_qspi driver. As cadence_qspi_apb_dma_read() is defined in
cadence_ospi_versal driver add a weak function defination in
cadence_qspi driver.
