nxp: adsp: enable usage of DCACHE API

With the transition to HWMv2, `CONFIG_CPU_HAS_DCACHE` is no
longer selected. This causes issues with Sound Open Firmware
since this configuration allows the usage of DCACHE-related
cache management operations. As such, to fix said issues,
select `CONFIG_CPU_HAS_DCACHE` on all NXP ADSP SOCs.
