[PATCH] accel/ivpu: Remove VPU_CPU_NOC_* register access from NPU6 onward

[Maciej Falkowski <maciej.falkowski@linux.intel.com>]

From: Karol Wachowski <karol.wachowski@linux.intel.com>

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.
