[PATCH] [RFC] spi: cadence-quadspi: Disable DAC on SoCFPGA

[Marek Vasut <marex@xxxxxxx>]

On SoCFPGA Gen5, DAC memcpy_fromio() in cqspi_direct_read_execute()
leads to data abort, disable DAC to avoid triggering it:

Unhandled fault: imprecise external abort (0x1406) at 0x0400d3e9
[0400d3e9] *pgd=00000000
