Subject: [PATCH 5.17 326/772] spi: cadence-quadspi: fix Direct Access Mode disable for SoCFPGA

From: Ian Abbott <abbotti@....co.uk>

[ Upstream commit f724c296f2f2cc3f9342b0fc26239635cbed856e ]

The Cadence QSPI compatible string required for the SoCFPGA platform
changed from the default "cdns,qspi-nor" to "intel,socfpga-qspi" with
the introduction of an additional quirk in
commit 98d948eb8331 ("spi: cadence-quadspi: fix write completion support").
However, that change did not preserve the previously used
quirk for this platform.  Reinstate the `CQSPI_DISABLE_DAC_MODE` quirk
for the SoCFPGA platform.

Fixes: 98d948eb8331 ("spi: cadence-quadspi: fix write completion support")
