accel/ivpu: Add support for Nova Lake's NPU

Add support for NPU6 generation that will be present on Nova Lake CPUs.
As with previous generations, it maintains compatibility
so no bigger functional changes apart from removing
deprecated call to soc_cpu_drive() function.

Quiescing TOP_MMIO in SOC_CPU_NOC as part of boot procedure is no longer
needed starting from 60XX. Remove soc_cpu_drive() call from NPU6 onward.

The VPU_CPU_NOC_QREQN, VPU_CPU_NOC_QACCEPTN, and VPU_CPU_NOC_QDENY
registers are deprecated and non-functional on 60XX. They will be
removed in future generations.
