[nrf noup] soc: nordic: Disable DCACHE

When the secure domain services are enabled. noup since the symbol SDFW_SERVICES_ENABLED are not available upstream. This is required specifically for the PSA crypto secure service but this is the most relevant Kconfig that I could use. This is temporary since we expect to add support for data cache later. This affects for the following secdom enabled targets: nrf54h20_cpuapp and cpurad nrf9280_cpuapp Signed-off-by: Georgios Vasilakis <[email protected]>
